Science Max | Tinfoil Boat | Season1 Full Episode

have you ever done a science experiment and wondered what it'd be like if you did it big i have my name is phil and i take your everyday science experiments and do them big this is science facts experiments at art this episode of science max is all about liquids what makes something float or not float oh no my loonies liquid density and super absorbent gel who wants to do an experiment with diapers liquids today on science facts experiments at large hey welcome to science max experiments at large i'm phil mccartney and hold on a second i'm just gonna change okay that's better now uh where were we all right let's go make a boat so you know that some things float and some things sink like rocks or wood or uh full water bottles and empty water bottles or uh carrots foam waffles screwdriver playing cards plasticine tin foil potato my watch wait that wasn't that wasn't supposed to go in there so how do you make a boat you make it out of something that floats right well most boats are actually made out of metal tin foil is metal and well it sinks but if you fold tin foil into a boat shape it floats and boats don't only float themselves but they can hold people and cargo in fact there's container ships crossing the ocean at this very moment that are holding thousands of tons of cargo and they're all made of metal which doesn't float it sinks so how do boats do it are they magic no of course not boats are science and here you can be science maximites get some tinfoil and cut it into the same size pieces and fold a couple different shapes of boats and see which one can hold the most weight before sinking and now it's time to max it out but before we do here's how you can fold your own tin foil boat in less than 15 seconds first take a square piece of tin foil then fold it in half fold one corner down and the other corner down then open it up and ta-dah you're done if you want instructions on how to fold a more complicated boat go to our website i have a feeling i'm going to need a few extra lab coats for this experiment like i was saying let's max out the tinfoil boat and find out a little bit more about why boats float ah okay well i'm i'm here at an indoor pool um which is not uh i wasn't expecting to be in the pool just yet but this is where we're going to build our giant tinfoil boat so why not who's here oh phil you're wet i yeah i thought i was gonna come in over there but i i came in on the water sled i think i had the coordinates wrong anyway this is lithia and she's from let's talk science which is all about science education right yes just like us so you're gonna help me max out the tinfoil boat i think i dropped it in the water hold on the tinfoil boat phil this is a boat well it looked a lot better before i came down the water slide but that's the idea and then we make it bigger what do you think i don't think it's gonna work well why not tin foil is very thin uh-huh and it might not hold the shape of the boat well i still think we should use tinfoil though why well because the small experiment was tinfoil and i bought all of this tinfoil then let's do it tin foil okay high five i will um i'll take the tin foil and you take that and um i'm gonna have to dry off at some point welcome to shipbuilding for pirates i'm swabbie and i've built some of the finest pirate ships for some of the finest pirates this side of the caribbean and i can teach you to do the same but first you need to know your basics mass and volume let's start with volume but not that kind of volume which of these two chests do you think has more volume right this one here which of these two balloons do you think has more volume right this one here volume is how much space something takes up which of these two chests has more volume hmm that's right they're the same but which of these two chests has more mass which is heavier mmm hard to tell isn't it but what if i told you that this one was empty and this one was full of treasure loonies now which one has more mass that's right this one these two chests have the same volume but this one has more mass this chest has more volume than that one but this one my loonies that chest does not have as much mass volume is how much space something takes up and mass is how heavy something is and when you look at them both together you're looking at density join us next time on shipbuilding for pirates then we'll look at how volume mass and density work together to make something float oh my precious precious loonies are you all right my fertis they can't talk so i'm not sure what they're saying so who's me and i get to work constructing a large tinfoil boat our first design is just sort of a square folded together out of a very large sheet of tinfoil simple but can i ride in it there we go a giant tinfoil boat just my size i don't know if it's gonna work uh it's too thin you think it's too thin i feel like this well what should we do do you want to test it let's test it okay good idea so here's here's the most important question do you want to test it or should i test it no no you test it all right here we go putting it in first test does it float on its own yeah floats on its own no problem if i just get in very carefully then it will work fine see if i if i'm if i'm careful about how i get in no it's fine see if i just get in like that oh my god are you okay wait a minute wait a minute it's sort of it's sort of no that's just air you know what went wrong it wasn't boat shaped i think if we make it look more like a canoe because canoes float if we make it look like a canoe it'll work great we need some support if we add a couple of structures in between then we add support to it i'll tell you what let's make a boat like i want to make in a boat like you want to make and we'll see whose is the best that's a good idea okay let's do that all right let's do it welcome back to shipbuilding for pirates i'm swabbie and now we know what volume means what mass means and that together it can tell you something's density now let's find out why things float let's let's say we're out to sea and my treasure chest gets swept overboard oh no but it's all right it floats because it pushes enough water out of the way displaces it to carry its mass but what if my treasure chest had more treasure in it well we're giving it more mass but not more volume too much mass and not enough volume and it will sink oh no my loonies you need more volume if you want to float more mass and that is why things flow i'm swabi and thanks for joining me on shipbuilding for pirates so the first version of the tinfoil boat didn't work out too well but my idea is to build a tinfoil boat more like a canoe to see if a different shape makes any difference tinfoil canoe very canadian very canadian the canoe part anyway i don't know about the tinfoil part so houston and i had a bit of a disagreement of why the last spoke didn't work i thought it was because it wasn't shaped enough like a boat so this one looks like a canoe what i thought is that it requires some structure structure so that it wouldn't fall together that's right and we'll see how it goes all right all right here we go did it work no okay your idea next did you know it's easier to float in salt water like in the ocean than it is in fresh water like a lake or a pool that's because not all liquids are created equal they have different densities this is fresh water or it doesn't have anything in it and this is sugar if i was to put one scoop of sugar in this water and stir it around until it dissolves now this liquid is more dense than before i put the sugar in here's an experiment you can do at home using liquid density this glass just has regular water with yellow food coloring in it this glass green food coloring and half a cup of sugar in it this one has a full cup of sugar in it and this one has two cups of sugar in it now when you do this at home you'll definitely want an adult to help you because you have to heat the water if you want to dissolve that much sugar in one glass of water i'm gonna put them all in one container you can do this at home and when you do i suggest you use a very small container because you have to be very careful when you put the layers in you can use a turkey baster or a straw when you put your finger on top the air pressure will hold the liquid in and you can just drop it in but these kind of take some time so i'm going to use the syringe of science i'm going to use the most dense liquid first because that's the one that's going to want to be on the bottom i carefully put it on the bottom of the container the next layer be very careful you'll see that the red and the blue aren't mixing because they have different densities the blue is heavier than the red we'll add the green and you can see even when it drips into the red it comes back up to the top because the green liquid isn't as dense as the red liquid and the denser liquids push the lighter liquid up and now we're going to add the yellow which of course has no sugar in it at all and there you go all the layers stay separate if you put it on a light you can really see it liquid densities now let's max it out the longest length of liquid layers 12 liquids all organized by density starting from the bottom we have honey corn syrup chocolate syrup maple syrup dish soap whole milk water dyed blue vegetable oil extra virgin olive oil rubbing alcohol baby oil and lamp oil liquid density i really really want to mix it up but it took me a long time to make this so i'm not going to our first two attempts at the tinfoil boat haven't gone so well husnia's idea is to make a tinfoil boat and add some more structure because the tin foil just wants to collapse when i get in it so we start with a large piece of cardboard on the bottom then we wrap the tin foil around it and shape it into a boat after that we add some supports across the top to stop it from folding in when we add my weight to it this boat feels a lot stronger than the one i was just doing i told you so how does all of this work so we got some support using broomsticks and then some cardboard paper and then underneath we have cardboard cardboard and so how will all of this help the boat not sink with me right the broomsticks will prevent it from folding this way yeah and you won't sink good the cargo will prevent it from folding this way and you won't sink again not sinking is my favorite thing to do in the tin foil boat all right so let's try it let's know are you gonna get in this one i'll tell you what phil if you get in and you don't sink i'll go after you deal all right all right here we go is no hold on one two three go another thing i learned is that a very light tinfoil boat can be very heavy when it's full of water i don't know if fixing it is in the cards i think we i think we're gonna have to build another boat so what do you think we should do let's add more structure more structure oh yeah what if we add like a metal rod around the outside and maybe some more metal rods and rims and we wrap it all in tinfoil and you think it'll work let's give it a try let's give it a try don't worry about it i've got this no i'll get it i'll get it sure okay who wants to do an experiment with diapers oh oh oh no no i'm serious you may have a little brother or sister at home which means you probably know where you can find some diapers but there are two things you need to remember first ask an adult if you can use the diapers for your experiment and two only use unused diapers okay okay so you take the diaper and if you cut it be very careful maybe get an adult to help you over some black construction paper like i have here and you shake the diaper over the construction paper you'll see that there's a little powder that comes out and this is the secret ingredient this is super absorbent gel what it does is it soaks up all the liquid and diapers are full of them and you carefully pour into a plastic cup like that now you can see i have already done it with a number of diapers it's important to use a plastic cup because it's a little messy although it's non-toxic it's totally safe but it's still easier to clean up by just throwing the cup away now add some water and what happens is this super absorbent gel absorbs the water and turns very quickly into a paste look at that now let's max it out five kilograms of super absorbent gel 500 liters of water now it is time to do science and i have my own stir sticks yep definitely coming along i'm not exactly sure if we're getting anything on this camera but i want to make sure it's recording yep it's recording there we go it is definitely turning solid well there you go the giant super absorbent gel experiment corey trevor i need some help getting out how many outfits have i been through in this episode how many outfits have i been through in this episode anybody have a towel there you go thanks buddy that's that's great husnia's idea of adding structure to the tinfoil boat was definitely right we just needed to go further so we did it again this time we made a much larger boat we started with a sheet of cardboard then wrapped the tin foil around and added some metal supports taped to the cardboard across the boat this way to make ribs as well as some other supporting pieces in the front and the back then another metal rod all the way around the top and finally supports across the middle all right feel how strong it is i'm really excited about this version of the tinfoil boat what we did is we used thwarts uh big hard pieces of wood that we did last time but this time we have ribs ribs right which are made of a cardboard a metal rod attached to it and and shaped and we did a whole bunch of them in the whole length of the boat and then we used all of this bendable metal and we have one that runs all the way around the gunnels and a whole bunch that run down the inside and we even used bike fenders at the front and the back of the boat to give it super rigidity so that it hopefully won't go like all the other boats have done so far are you ready husnia let's do this one two three lift all right let me get over it floats but that doesn't tell us anything because they've all floated at this point it's only when i i get into it okay here we go all right hey it works all right oh it's working look at that it works perfectly the tinfoil boat experiment has been done science max experiments at large what do you think museum the only reason i got into this book because i knew it's gonna work really oh yeah so you knew you would never get wet see i don't think that's fair i think it's time that you that you got wet yeah i think we should go i think you and i should just get wet right now whoa you're still driving that is so unfair science max is a show where we take small experiments and do them big if you want to try these experiments yourself go to our website for instructions but not all the experiments on science max are the kind you should try at home this one yes this no try this don't try this a big yes a big no i i don't know how you could possibly do this one at home and remember if you're ever not sure ask an adult thanks for watching max experiments at large science i don't know what you're saying i don't speak treasure chest the one thing i'm really trying not to think about is that this is the stuff that's in diapers let me talk to your brother don't talk with your mouth full you
