Making transparent wood

this video has been sponsored by kiwico but more about them later a couple years ago i attempted to make transparent wood which is supposed to be almost as clear as glass but much stronger and shatterproof my main reason for making it though was mostly just because i thought it looked cool my results were kind of okay and i was able to make a few almost decent pieces but i had a lot of problems with the process it was a lot more difficult than i thought it would be and none of my pieces were as nice as i would have liked i also really wanted to make some larger ones but every time i tried it it ended up cracking after a day or so instead i settled for some smaller ones which didn't crack and they just became really warped it was transparent though and at the time i felt that it was good enough but this was what it looked like after sitting around for several months they were all yellow and cracked and clearly this wasn't the best method so i've decided to try it again and there was recently a paper about transparent wood that kind of went viral i'm not going to be using their method though and i'll mention a few reasons why throughout the video instead i wanted to try something from a paper published in 2016 which was actually two years before my first attempt i have no idea how i didn't find this back then but it seemed to avoid all the problems that i ran into to get started with it the first thing that i needed was a piece of wood or more specifically a piece of balsa wood what was nice was that i was able to find it at a local art store and it was already made into a thin strip for the thickness of the strip i went with an eighth of an inch which was about 3.2 millimeters the first thing that i had to do was cut it using a knife and i made some small squares that were about two centimeters by two centimeters this size was kind of arbitrary but i figured it was best to start small and then scale it up now on a quick side note a lot of papers including the one that went viral made the pieces a lot thinner and they were usually at most one millimeter i felt that that was way too thin though and at that point it was getting closer to being paper than wood also the last time that i did this the pieces kind of fell apart and i was worried that it was because i had made them too thin but anyway when i was done cutting them i dropped them onto a dish and i put them in an oven to dry the paper said to keep it at 105 c for 24 hours to get rid of any moisture in the wood i think they were already pretty dry though and when i pulled them out the next day they looked exactly the same now what i had to do next was chemically treat the wood and remove something called lignin and i also had to bleach them white in my last attempt i pulled out the lignin using a boiling solution of sodium sulfite and sodium hydroxide and then i bleached it using 30 hydrogen peroxide that method seemed to work okay but i didn't find that it was very efficient doing it in two steps the method that i wanted to try though use sodium chlorite which was able to do both at the same time also in general it's a lot easier to buy sodium chloride than it is concentrated hydrogen peroxide at least here in canada anything above 30 peroxide is controlled because it can be used to make explosives and if you do manage to buy it you can sometimes end up on a list this is very different than the sodium chlorite which has little to no regulation and you can just buy it online the reason that it's so available though is kind of unfortunate it has a legitimate use as a disinfectant or cleaner but more often than not it's sold as some sort of alternative medicine people use it to make something called miracle mineral supplement or mms for short and they claim that it can cure everything from cancer to autism the only problem though is that at least chemically it's kind of similar to drinking dilute bleach there's no real evidence that it does anything besides destroy your insides so now just like that other time when i bought cyanide almonds i was a bit conflicted because i didn't want to support a market like this however it was on amazon and it was by far the cheapest and easiest way to get it so when it eventually arrived i was able to put together my wood treating solution according to the paper i had to make a one weight percent sodium chloride with acetate buffer solution with a ph of 4.6 at adc at first glance this kind of seemed like a complicated and maybe hard thing to do but it was actually relatively simple to put it together i started by adding 125 ml of water followed by 1.67 grams of sodium acetate and 1.15 ml of acetic acid i then turned on the stirring and when all this had dissolved i was already almost done i only had one more ingredient to add which was 1.3 grams of the sodium chloride when all of this had also dissolved i added a thermometer turned on the heating and waited for it to get to about adc as it warmed up the acetic acid was slowly reacting with the sodium chlorite and releasing chlorus acid which quickly broke down into chlorine dioxide when it eventually got to adc i turned off the stirring and i dropped in the pieces of wood i did my best to spread them out but unfortunately there just wasn't enough space so i poured everything into a bigger beaker as it sat there the chlorine dioxide solution was attacking and dissolving one of the major components of the wood called lignin in general wood is around 25 lignin which is kind of like a glue that holds the wood fibers together by taking it away i was making the wood more porous and i was opening up the space between the wood fibers i was also getting rid of the natural yellow color that wood has which mostly comes from the lignin according to the paper this process should bring the lignin content down from the 25 that i mentioned before to only about 3 what i was supposed to be left with was mostly cellulose and hemicellulose which were naturally colorless about 7 hours later they eventually looked almost completely white and i felt that it was done so i pulled them all out and i dropped them into some distilled water i then left them overnight for all the chemicals to slowly diffuse out the next day i filled another bowl with 100 ethanol and i transferred them all over i waited another day and then i did the exact same thing with a 50 50 mixture of ethanol and acetone and then with pure acetone as far as i know the paper doesn't really go into detail as to why all these solvent washings have to be done but i think the major reason is to just get rid of the water after a few days of mostly waiting i was eventually left with some little dry pieces of wood which were hopefully close to lignin free they clearly still weren't transparent though and that was because i still had one major step to do which was infuse them with plastic however before doing that i took a closer look at one of them the first thing that i tried was bending it a bit to see how strong it was the last time i did this the pieces all became super soft and bendy and i was kind of expecting the same thing to happen however they were actually still pretty tough and they felt similar to before the treatment i'm not exactly sure whether this was because i used balsa this time or if it was because of the different process my opinion though is that it was probably a combination of the two either way it was a pleasant surprise and it meant that it was probably possible to safely make pieces that were both thinner and larger something else that i noticed was that even though they weren't exactly transparent they were definitely more transparent than regular wood it was still way too hazy to see any details through it but it was vaguely possible to see something but anyway it was now time to try and hopefully make it completely see-through to do this as i mentioned before i had to infuse the wood with some sort of plastic and the last time that i did this i used an epoxy resin there were at least a few things though that i didn't like about the epoxy the first was that it was a two-part mixture and the moment the two parts were mixed together they would start to react this gave me a limited time to work on it before it started to harden and i found that this made things really rushed and it was hard to do a good job the second and probably more important reason is that epoxy has a tendency to turn yellow this is often because of exposure to uv light but i kept mine in a cupboard and it still somehow happened what i did find interesting though was that a lot of papers on transparent wood used epoxy including the one that recently went viral in fact they often use the exact same stuff that i used in my opinion though this was a major problem especially considering that transparent wood is supposed to be a potential replacement for glass windows windows are constantly exposed to the uv in sunlight and if epoxy were used you'd probably end up with a nasty yellow window this was one major thing that i liked about the paper that i decided to follow they didn't go with epoxy and they instead went with something called methylmethacrylate or mma for short when this polymerized it would make acrylic also known as plexiglas and it didn't have the same yellowing issue its polymerization was also triggered by heating it and this meant that i could actually choose when i wanted it to harden this all sounded pretty good to me so i ordered some methyl methacrylate as well as an initiator called aibn unfortunately i couldn't just add them both directly to the wood and i first had to partially polymerize the mma to do this i started by adding a very small amount of the initiator after that i poured in about 50 mls of the methyl methacrylate and i dropped in a stir bar i then turned on the stirring and when everything had dissolved i moved the flask to a hot water bath when the temperature got above about 40c the initiator was supposed to start breaking down and releasing free radicals these free radicals would then attack a molecule of mma which would turn into a more reactive form which could attack another molecule of mma this process known as polymerization would then keep going and it would slowly grow chains of methacrylate molecules the length that these chains grew to was mostly determined by temperature and time and the paper said to react it for 15 minutes at 75 c so after 15 minutes i pulled it out and i dropped it into some ice water [Music] this quickly dropped the temperature and it was supposed to stop the polymerization at whatever level it was at i let it sit there for about 10 minutes and i was now ready to add it to the wood to do this i got out my vacuum chamber and i added some of the pre-polymerized mma to a small dish i then dropped in one of the pieces and i made sure that it was completely submerged i also covered it with another dish because this step can sometimes splash a lot and i closed the chamber after that i turned on my vacuum pump and it started to bubble because air was getting pulled out of the wood then as i pulled a stronger vacuum it started boiling off the acetone as well as some of the unpolymerized mma over the next 15 minutes the bubbling gradually slowed down and eventually became more or less constant i kept it going for another 15 minutes and then i released the vacuum this should have caused the mma to start rushing into the wood and filling all the spaces that the air and acetone used to occupy i really thought that at this step it would have started looking transparent but it looked almost exactly the same this didn't concern me too much though and i thought that maybe it only cleared up when the mma was fully polymerized i then did two more vacuum cycles of 15 minutes and at this point the wood should have been completely filled with the mma now what i had to do next according to the paper was sandwich it between two pieces of glass so what i did was drop it onto a glass square that i found on amazon and this part was actually the main reason why i chose to do this method it was the only one that seemed to wedge it between glass and their final pieces were nice and flat when i looked closely at almost every other paper that i found their samples were wavy or warped but anyway i then put another glass square on top of it and i wrapped it all up with aluminum foil i wasn't exactly sure what the aluminum foil was for but the paper said to use it so i just did what it said with it all nicely packaged i put it in my oven that i had preheated to 70c and i left it in there for four hours as it sat there the methacrylate was supposed to start polymerizing again and when all of it had eventually reacted i should have been left with solid acrylic when i came back and took it out of the oven i was hoping to see a super nice and beautiful piece of transparent wood but that of course wasn't what i saw it's uh it looks the exact same looks like it didn't do anything to it okay so that was nothing short of a complete failure and i was gonna have to try again the mma had all apparently just disappeared but that was what the pre-polymerization was supposed to be preventing by polymerizing it a bit and making some short chains it should have been making it a lot harder for the mma to vaporize and so that it wouldn't just disappear in the oven something clearly went wrong though and i thought that maybe it was the initiator it was possible that it might be old or bad or something so this time i tried using twice the amount unlike last time it started releasing some small gas bubbles and this was all nitrogen it was forming as the initiator was being degraded and it was a good sign that it was actually working the fact that i didn't see this happen last time probably meant that i'd barely done anything over the next 15 minutes it also got thicker and thicker which was another good sign and it meant that it was actually polymerizing like before i then pulled it out and i dropped it into ice water when it got to around room temperature i added the thicker mma to the dish i then dropped in another piece of wood added a bit more mma and started the same vacuum cycle after turning on the vacuum though i realized that i'd gotten a bit too excited and i'd forgotten to add the cover dish this wasn't a huge issue though because besides that first pop it wasn't actually splashing very much and i just added it after the first cycle unlike last time as it continued pulling a vacuum on it the mma slowly got thicker and thicker i think this was because it was pulling off a lot of the unpolymerized methacrylate and concentrating the partially polymerized stuff this evaporation was also causing it to cool down which would thicken it even more after the last vacuum cycle the wood still wasn't completely clear but it did look a bit more transparent i then took it out squished it between some new glass squares and threw it in the oven i was again hoping that it would just magically clear up and look amazing but that wasn't the case i mean it was definitely better than before but i wouldn't call it good also a major problem that i was noticing was that it looked like the acrylic was stuck to the glass as far as i know this issue was never mentioned in the paper and i kind of just assumed that as it cooled that it would pop itself off however that clearly didn't happen the good news is that it actually worked this time kind of the bad news is uh it sucks even at room temperature it was completely stuck and to get it off i made some score lines in the glass i then got out my hammer and i carefully smashed it to pieces i also did the exact same thing to the other side and i was eventually able to free my piece there was unfortunately still some glass stuck to it though so again i carefully hit it with the hammer after that i used the dremel and i cut off the extra bits of plastic i also sanded it just to clean it up a bit the final piece was only kind of transparent and it was a bit disappointing what was good though was that it was completely flat and it didn't look bent at all when i tested it i had to use a lot of backlight but it was possible to see through it it was still super hazy though and a lot of it was still very yellow this yellowness told me that i clearly hadn't treated the wood pieces for long enough and there was still too much lignin in there i think the biggest problem though was that i'd made the pieces way too thick i did this because i was really worried that they were going to fall apart but they turned out to be totally fine so this extra thickness wasn't really doing anything and it was basically just making it hazier it was making the whole thing a lot less transparent even in the non-yellow parts that kind of looked okay based on this first and kind of successful run i had a bunch of issues to fix and the first thing that i did was cut some thinner pieces i was clearly a bit too ambitious trying to make them so thick and they for sure had to be reduced but i didn't want to go all the way down to one millimeter i instead settled for 1.5 millimeters and i found these thinner balsa strips on amazon i then did the exact same process as before except this time i made sure to keep going until they were completely white this ended up taking about seven hours and when i felt they looked okay i dropped them all into some water and i compared them to the older pieces the difference was pretty obvious and what i had now was definitely a lot better i then dried the pieces using solvents but this time because it was way cheaper i used 99 isopropyl alcohol instead of the ethanol this again took a few days and when it was done they were already kind of transparent now for the pieces of glass i stopped using those thin and flimsy ones i instead found these coasters on amazon which were much thicker and hopefully a lot stronger i also decided to spray them with some mold release to prevent the acrylic from getting stuck to the glass the only issue was that i had no idea how to properly apply it and i ran into a bunch of problems after a few small tests though i found something that seemed to work both of the plates were first cleaned with some alcohol and then i lightly sprayed them with the mold release after that i used a brush to spread it out and to try to give it an even coating i let it evaporate for about 10 minutes and when it started beading up i wiped it around to even it out i then added a second layer by repeating the exact same thing and when that was done i polished it with a microfiber towel this left me with a pretty shiny and clean surface which the acrylic hopefully wouldn't get stuck to with this all ready i prepared some more methyl methacrylate but even with twice the initiator it didn't work in 15 minutes it instead took 30 minutes to thicken and i have no idea why but either way i now had everything that i needed and i started treating one of the pieces i did the exact same thing as before with three vacuum cycles and when it was done it was looking pretty good i then carefully dropped it onto one of the new pieces of glass sandwiched it with another one wrapped it and put it in the oven with all the changes i was extremely hopeful for this one but it of course also kind of failed the wood was definitely more transparent but the glass had somehow tipped over the combination of the stronger glass and the mold release seemed to work though and i was able to easily pop off the top one it actually worked however the actual piece of wood unfortunately didn't pop off as nicely this made it even sadder than i had hoped why but at least the problems were quite fixable so i decided to quickly try it again this time after dropping on the treated piece of wood i added some spacers that i'd cut out of the untreated balsa i figured it was an easy fix to stop the glass from tipping over and i also used aluminum tape to hold it all in place this felt a lot more solid than before and it was way better than just trying to balance everything on a piece of wood in the middle also because of the issue before with the piece of wood still getting stuck i treated the glass with four layers of mold release instead of just two the result from this run finally wasn't a complete disaster for a second though i did think that the piece was stuck again but that wasn't the case the piece from this one was even better however it was still a bit problematic the side that was touching the bottom plate was almost completely smooth and shiny but the other side looked like it was missing acrylic in the middle i wasn't sure why this happened and i thought that maybe it was just because the surface of the wood wasn't perfectly flat it was possible that the glass was only touching it in a few high spots and there was a slight gap between the rest to fix this i thought that it might work to just put some weight on it and to really squish it together so now for the hopefully final attempt i did it pretty much in the exact same way as the last one i then put it in the oven and for the weight i needed something that was small but really heavy i initially had no idea what to use and i probably spent 15 minutes just walking around the room looking for something what i ended up finding turned out to be perfect though and it was the five pound tungsten cube that i had randomly bought over a year ago i then waited the usual 4 hours and when i opened it up i was pretty happy with what i saw i let it sit for about 30 minutes to cool down and then i took it apart it was a bit stubborn but it was pretty easy to crack it open with a screwdriver like before i got rid of the extra plastic using a dremel and i also sanded it a bit this one was by far the best result and i felt that it looked pretty good the top side was still a bit rough but the bottom was close to perfect so the extra weight apparently didn't do very much for the top but it seemed to help the bottom now when i tested it it was way more transparent and i could easily read the text through it my only issue with this piece was the rougher top and i started thinking that maybe the top just had problems however i thought that the fix was relatively easy i figured that all i had to do was just selectively treat the top rough side by painting some more methacrylate on it i would then do the exact same vacuum cycle and i would squish this treated side against the bottom glass in my mind this made total sense and i was almost certain that it would work so i did the really smart thing and i completely skipped trying it i instead just assumed it would work and i jumped right into scaling things up i honestly thought that it was just going to be really straightforward and easy because i assumed it was just what i'd done before but bigger however that turned out to be a terrible assumption i quickly learned that the larger scale had a whole bunch of its own issues that never even occurred to me for example any gas bubbles that formed now had a much harder time escaping especially if they formed near the middle of the piece this gave me a couple attempts where there were clearly some bubbles that got trapped i also had one run where the piece cracked as it was cooling down and another one where the methacrylate drifted away from it while it was in the oven there was also my favorite one which absolutely refused to separate from the glass and i had to help it a bit i think the saddest part though was when i found out that it wasn't gonna work to selectively treat one side i mean it did technically work and i was able to get two sides that were smooth but it also introduced a bunch of weird cracks i did think it was kind of interesting though and it had a cool effect when i turned the piece 90 degrees but with all that being said the main point here is that scaling it up turned out to be a lot trickier than i thought on the surface the process appeared really simple but every small detail seemed to matter eventually though after a week of what felt like constant failures i came up with a process that i felt would work to try it out i cooked up what i was hoping would be my last piece and i soaked it in the same solvents when that was eventually ready i started making the pre-polymerized methacrylate and this time i used a lot less initiator instead of twice the amount i now only use 20 percent more also in general i found that this was actually one of the hardest parts this was because i found that there was an optimal thickness or viscosity that i had to bring it to but it never seemed to take the same amount of time sometimes it was ready after as little as 15 minutes and other times it took closer to 40. it's very possible that i was just doing something wrong but either way i ended up having to use a method that wasn't exactly super scientific i basically just got good at shaking it around and looking at it and knowing when it was ready when it eventually got to what i felt was the right thickness i pulled it out and i dropped it into ice water when it had cooled down to around room temperature i poured it all into a large dish i then dropped in the piece of wood and i made sure that it was completely submerged now i again had to do the three vacuum cycles on it but this time i had to do them for much longer at around 45 minutes each i also pulled the strongest vacuum that i possibly could to try to get rid of all the acetone as well as any unpolymerized methacrylate i found that this was important because otherwise they would boil off as they sat in the oven and potentially introduce bubbles there was a side effect to the extended vacuum though and it caused the methacrylate to thicken a lot more this made it very important to start with methacrylate that wasn't too thick otherwise it would sometimes start to solidify before the end of the third cycle when it was done i pulled it out and i dropped it on a much larger glass plate this plate was originally meant for 3d printers and i had already treated it four times with mold release i also made sure to completely polish the entire thing any unpolished parts could cause the acrylic to stick and this was why one of my pieces ended up cracking it could also cause it to not separate at all and i really didn't want to have to smash any more glass in most of the other runs i used small wood spacers to help stabilize the glass plates but i realized that they were actually sabotaging me almost the entire time i think it took me way too long to find this out but apparently methyl methacrylate contracts as it polymerizes and it can lose up to 21 percent of its original volume this meant that my piece was potentially shrinking quite a bit as it cured and with the wood spacers in place it was pulling itself away from the upper glass plate this made it so that all the weight that i had added was basically doing nothing and i had to stop using them when i first realized this i thought it was going to be a problem and that i'd have to come up with some other way to balance the plates however it turned out that on this larger scale they weren't even needed the piece of wood was now big enough that there wasn't really an issue balancing the glass plate on it and as long as i kept it more or less centered it was totally fine at this point things were looking pretty good and i put it in my oven i then loaded it up with a much larger tungsten cube which was coincidentally the perfect size and it weighed about 40 pounds i had bought this one around the same time as the smaller one and i had originally planned to use it for a video i never really ended up getting around to doing that however i like to think that this technically counts with everything in place i made sure that everything was all level so that the methacrylate wouldn't drift then when i felt that it looked good i closed the oven and i turned it on in a lot of the other runs i had preheated the oven but i found that it worked better when it heated up slowly from room temperature now it was just a matter of waiting and i was pretty anxious to see the result when i came back to it four hours later i pulled it out of the oven and i was kind of happy with what i saw i then waited for it to cool down and slowly separate from the glass this part can sometimes be surprisingly loud and it sometimes really sounded like something was breaking there was also one time where the acrylic actually did snap so i couldn't help but be a bit nervous when i came back to it about 30 minutes later it thankfully wasn't broken and i cut all the pieces of tape to open it up i pulled on the top plate and it came off pretty easily i was a bit worried that the piece itself would be hard to remove but it also came off without much effort now looking closer at what i had made and it was kind of bad and good at the same time the part that was touching the bottom plate was almost perfect but the top wasn't nearly as beautiful i mean it was still by far the best result that i had ever gotten especially when you compare it to what i was getting before even without the spacers though the top part still wasn't turning out as well as i had hoped and i think that was just because of gravity as it sat in the oven the methacrylate was slowly sinking down and away from the top plate and there wasn't much i could do to stop that thankfully though i felt the fix was relatively easy and i just had to treat it a second time to do this i first had to clean it up a bit by cutting off all the extra plastic i then lightly sanded both sides and when i felt that it was good i dropped it into some freshly prepared methacrylate i then did the typical three vacuum cycles on it but this time they were much shorter this was because there wasn't any acetone to get rid of and i only did them for about 10 minutes when it was done there was unfortunately a small part in the bottom corner that refused to fill with resin however i was kind of hoping that it would just magically disappear in the oven i then dropped the piece onto the glass plate and i made sure to flip it so that the side i wanted to fix was against the bottom plate i did this because the bottom side always seemed to turn out nicer and i thought this might help after that i added the upper plate and i taped it all together i then loaded it up with the cube again made sure that it was level and turned on the oven i was again really anxious to see how it turned out and i patiently waited the four hours when it was done i took away the cube and i was almost immediately disappointed to know exactly how bad it was though i first had to wait the 30 minutes for it to cool down it didn't end up being as bad as i thought but it also wasn't great and to be honest i kind of expected that this process was just way too unpredictable and the likelihood of having both sides come out perfect was extremely low to a certain degree i was hoping that luck would be on my side and a miracle would happen but i really didn't expect it to up until now my main goal was mostly just to fill the wood with acrylic and to get it to the point that it only had minor imperfections this was almost exactly what i had now and to make it nice i figured i just had to use some sandpaper i started wet sanding it with 600 grit paper but it wasn't coarse enough and i ended up going down to 320. i kept going until it looked like the surface was perfectly even and then i slowly moved up to finer and finer sandpapers until i got to 2500 at this point it was starting to look pretty good and for some reason i feel like it actually started looking more like a piece of wood it was still a bit too hazy though because the surface was still a bit rough so what i had to do next was polish it and based on what i saw online this plastic polish by novus seemed to work pretty well the instructions were pretty simple and it's said to start with the number three i spent a few minutes polishing both sides and when i felt that it looked good i washed it all off and i moved on to the number two this one said to keep going until the polish disappeared and i again did it on both sides i then wiped it down with a microfiber towel and i finished it with a good rinsing now with it all polished and clean i cut off the extra plastic [Music] after that i sanded the edges to clean them up a bit and this was the final result it was honestly way better than i ever thought it would be and i was really happy with how it turned out it technically still isn't perfect but i think that's kind of a good thing i think all the slight imperfections on the surface actually make it look more like a piece of wood and less just like a slightly hazy piece of plastic also i think the sanding made the grain of the wood much more obvious which i thought was really nice now for a quick transparency test like i did before and it was way better the text below it was extremely easy to see and i didn't even need a backlight one thing that i did notice though now that it was against the white paper was that it did have a slight yellow tint to it despite this though and all of its flaws it was still better than i ever expected and i guess my revisit was successful i mean it was one of the most finicky and frustrating projects i've ever worked on but it turned out almost exactly how i wanted it to it also ended up still looking like a piece of wood and not a chunk of plastic which i was really happy about in the future i think i would like to try and scale things up even more and it would be really cool to make a proper full-size window however for now and at least for a while i'm kind of done thinking about transparent what now on a bit more of a personal note i mentioned in my last video that i was moving to a new space and building a new lab and well it's turned out to be way more work than i thought and for those of you wondering where i've been i've basically just been doing construction for the last few months it is very close to being done though which i'm very happy about what i'm not as happy about is how much it has cost and it's been way more expensive than i could have ever imagined so now more than ever a big thanks goes out to all my supporters on patreon and to kiwico for sponsoring this video if you haven't already heard about kiwiko they make these really fun and engaging monthly crates that are designed to give kids a hands-on experience in science technology engineering arts and math let's do this every crate comes with detailed kid-friendly instructions as well as all the supplies that you need to put it together so you never need to make any runs to the store the projects that they have are also extremely well thought out and i'm actually really impressed with what they offer for example this one that i'm putting together is supposed to be a fully functional ukulele however i've never played a ukulele so we'll see how functional it ends up being yeah i got some practice to do the main thing that kiwico offers is monthly crates and they have eight subscription lines for a variety of different ages however they also have a shop where you can just buy single projects and i kind of want this experiment one both all that being said if you're looking for a fun project for your kids or even yourself i recommend checking out kiwi cow if you decide to try them out you should also be sure to use my special link in the description kiwico.com nile red to get 50 off your first month of any crate that's it as usual a big thanks goes out to all my supporters on patreon everyone who supports me can see all my new videos at least 24 hours before i post them to youtube you'll also get access to all the older videos that i had to take down and if you support me with five dollars or more you'll

Kind of a waste of time if the original wood weighed 2g and the finished piece is 15.45g with the wood lignin removed, it’s essentially all acrylic with bits of wood fibre in it.

[u/SpidersArePeopleToo]

So, does the cellulose structure add much strength to the resin? (Otherwise why not just use resin without the wood?)
