ROCKET ENGINES FROM HOUSEHOLD STUFF! ELEMENTALMAKER

today we're going to turn stump remover powdered sugar sulfur and a little bit of kitty litter into working rocket engines so the first step in building your rocket engines you're going to want to gather your supplies for the rocket fuel so here I have Spectre side stump remover potassium nitrate has a bottle of stuff that I already ran through the blender to make it really finely powdered like the consistency of powdered sugar is what you're looking for second little fuel or part of the fuel is powdered sugar this is actually acting as the fuel that the potassium nitrate oxidizes so the potassium nitrate supplying our oxygen powdered sugar is acting as their fuel and then we're also going to use a little bit of sulfur that's to increase the burn rate so it's acting as a burn rate catalyst other things you're going to meet some bentonite clay so this was just some super cheap kitty litter from Walmart that I ground up in a blender and then I also melted in some paraffin wax and that gives it a really nice consistency that tamp down really well forms really solid end plugs you're also going to want some two and a half inch sections of PVC pipe this is a 1/2 inch inner diameter PVC scheduled 40 you're going to want a 5/8 inch dowel now the thing here is the half-inch pbc that's a nominal rating so it's not actually going to be having the inner diameter you can see here is actually more more along the lines of 0.6 so take our 5/8 inch dowel you're going to want to sand it down until you get a good fit through the point six you're going to have to take off a little bit of material just try to do it nice and even like not very hard to do and we're ready to make rocket engines so you're going to want to measure out 67 grams of potassium nitrate good idea to keep this stuff in an airtight follow because it does pick up moisture out of the air very effectively it's very hydro scopic we are almost 67 on the dot 27 grams of sugar pretty darn close and then six grams of sulfur so you'll notice my sulfur is a little clumpy but it is very very finely powdered so it'll mix in just by subtract and this is our rocket fuel so now we just got to mix it up really good make sure it's very a ball combine no big chunks and and at that point we will have a usable rocket fuel so I'm just going to mix this up for a few minutes make sure any chunks are broken up really well wouldn't be a bad idea to throw this in a maybe a Tupperware container and shake it off really good next step is going to be to take your dowel that you've sanded down to match the inner diameter of the PVC pipe and two and a half inches from the tip of the dowel you want to mark a line and then another line a half inch from that that'll be your clay section you'll have a one-inch section that'll be your mix then a quick quarter inch section that will be our delay mix so that's actually going to be one part sodium bicarbonate baking soda with ten parts of mix and you can adjust that accordingly if you want to faster or a longer delay and then we're going to put another half inch section of clay behind that so for this example piece I'm going to be using some clear PVC pipe you can get this stuff right on Amazon it's really cool and if you're doing this with your son or something it's awesome to be able to actually you know pop glue this thing down to a piece of wood watch from a safe distance but you can actually see the inside of the combustion chamber with the clear PVC so that's really cool so to get 1/2 inch of clay it's going to be roughly one teaspoon of a bentonite clay total so each one of these is a half it should bring us right up to this half inch mark my little bit more all right right wherever we want to be now we're going to start adding the rocket fuel and you want to regularly compress this stuff down with very high viscosity and it is currently summer so it's very humid we're all met a bit more mix little too much that's perfect brought it right to the line you can see that so now I pre-made some delay mix you literally just want to take a small amount of your standard mix and add in some baking soda to slow down burn right now we're going to add the next bit of clay this should leave a small amount of head space at the top of the engine and that's important because that's where our first start is gone or ejection charge she's going to sit and if you don't have an ejection cutters you're not going to have anything more than a big long dark a little bit more clay there we go so you can see here focus we have the section of clay section to mix our delay in here and then another section of clay now we just got to drill out the core with a 5/32 drill bit and then we'll drill out a little hole just enough to touch the delay section and then we could add a little bit of black powder there and that'll act as our ejection charge you can see I got the factory second drill bit here and I secured a piece of tape one-half inch or one and a half inches from the tip and that's going to let us know when to stop drilling now I have it secured in the little truck here you can easily stand it up and do it by hand as long as it's vertical in the center normally I would not touch a weaving girl I'm such a low-speed still is a dumb thing to do just one go nice and slow your propeller this is the live rocket so too much purchasing it could heat up they could go home so we got our nozzle drilled and then we're going to go through the back and just push off I think just got the mix there so we've got our finished engine here or just about finished all we have to do now is add the ejection charge I'm out of black powder so for this example I'm just going to use a little smokeless powder now this wouldn't be optimal to use in a in an actual engine needs a lot of confinement and pressure to actually burn quickly so this probably wouldn't pop your parachute black powder is definitely better for that put a of this tamp a little paper towel in there hold it in place alright there's our finished engine let's go give it a test fire so our first attempt wasn't the hottest so what I did is I made another one exactly the same but I did a core length of one and a quarter-inch instead of one and a half and that should improve the timing of the delay ejection so the last one definitely would have gotten your rocket in the air but it would have ejected a little bit prematurely premature ejaculation not something you want your rocket to have let's give this one a shot much better so that's exactly what we're looking for so ignore what I said about the one and a half inch the one and a half inch depth for the drill stop set that at one and a quarter and you will have a perfect rocket action now here we have a little bit of the rocket fuel we made so 67 parts potassium nitrate 27 parts powdered sugar and then six parts sulfur so most of what's going on here is basically the potassium nitrate is oxidizing the sugar into carbon dioxide and it's also making some potassium carbonate now there's a whole bunch of other side reactions going on with the sulfur and what the sulfur is in there for is to increase the burn rate so let's give this fuel a little test shot so you can see that pearl is pretty vigorously not quite as quickly as a good black powder but but it's up there alright guys well I really hope you enjoyed the video you know we might be building rocket engines here but assuring rocket science so get out there by some stump remover make your own have a good time go out launch some little rockets with it and if you like the video please hit the thumbs up and consider subscribing if not no worse and hope you have a good day
