Science Max | Bread Experiment | Season 1 Full Episode

have you ever done a science experiment and wondered what it'd be like if you did it big i have [Music] my name is phil and i take your everyday science experiments and do them big this is science facts experiments at arch [Music] newton's third law is the science behind balloon powered rocket cars it's also the science behind a maxed out rocket car that i can ride plus bowling balls and an interrupting sign today on sciencemax experiments at large greeting science maximites i am film aquatic and this is science max experiments at large today we're going to be experimenting with the balloon powered car here's how it works it all has to do with newton's third law [Music] newton's third law for every action there is an equal and opposite reaction uh we don't we don't have to do this now we can this is all for later we can build the cars first and then we can uh let's go over here so how do you build a balloon-powered car well i suggest you be science maximites because there is any number of ways you can build a balloon powered car you do not have to follow my design you should come up with one of your own it may even be better than the one i built but i will give you some tips though that make it a lot easier first of all you need something to stick your balloon on that has an opening on it i used a turkey baster for this car i just pop the top off and remember to tell an adult that you're using the turkey baster and then you stick the balloon on there and it allows you to attach something to the car and it also makes it easier to blow up the balloon you can use any number of things even just uh any kind of tube that you find lying around it helps you attach the balloon to the car and it helps you blow up the balloon way easier the other thing you should think about when you make your balloon powered car is how you're going to make the wheels roll once you've decided on the base of the car you could use anything even just a piece of cardboard like this you can do your wheels in two ways the first way is to attach the wheels to the axle this is how i made the axle of this car i used a shish kebab skewer and i stuck it inside a straw just like that and then i attach the lids to the shish kebab skewer so the lids and the shish kebab skewer are attached and they rotate in the straw that's one way to make the wheels turn the other way is to tape down the axle or whatever you're going to use uh and have the wheels spin around on the axle two great ways to make your wheels turn and it really kind of depends on the wheels you're using you can make your own design and keep refining it and making it better and faster or do what i like to do and make a whole bunch of different cars so we've got this one duh this one i made out of paper plates and this is a snorkel awesome this one is the rock car because there's a rock on it i've got uh the dragster model it's a long broom handle and it might not work that well but who knows and this is my favorite design this made out of waffles and an ice cube tray this is why i make a whole bunch of different cars because i can race them sunday sunday sunday and the science maxadrone it's the balloon powered car winner take all drag race off awesome first step the eliminator [Applause] better late than never it's the procrastinator [Music] [Applause] crushing the competition it's the terminator [Music] feel the chills of the refrigerator and last but not least the um regurgitator [Music] well when you build your balloon-powered cars you can figure out what worked or what didn't work and try modifying your designs to make them work even better that is science and now we're gonna max it out because this is science max experiments at large so we're gonna take that small balloon-powered car that we just built and we're gonna make it much much bigger i'm going to go to the center for skills development and training and we're going to use the science behind the small balloon powered car and we're going to make it big that science is newton's third law but there's plenty of third world there's plenty of time for this later we're not doing we're not doing this bit now we're doing that bit in a minute so we could no i said we're doing it later we're doing it but you know [Music] oh hi sarah hi phil this is sarah and she's got a master's degree in physics from mcmaster university that's right and we're going to be talking about newton's third law look up look out duck uh sorry sorry there was a sign that kept coming in um never mind newton's third law well what is that for every action there's an equal and opposite reaction right so how does that work with our balloon car ah cool okay so if you blow up the balloon what's gonna happen when you release it is the air is gonna push out with a certain force which in turn is gonna cause the cart to move forward with the exact same force yeah works great so how come it doesn't work with my rock car ah wow well actually it did work so the balloon still pushes with the exact same force which causes the cart to have the exact same force pushed forward but your rock is really heavy so you probably didn't see it move oh so a lighter cart works better with the same amount of force that's it well there you go newton's third law what newton's third law for every action there is an equal and opposite reaction i'm really starting to dislike that sign phil are you okay yeah i'm fine our small balloon-powered car works because of newton's third law for every action there's an equal and opposite reaction the air pushing out the balloon this way pushes the car with the same amount of force this way so in order to max it out the plan is just to get a bigger wheeled cart and a much bigger balloon so everything should work out the same okay so oh i thought what we would do is i would in order to max out the balloon-powered car what we need is a cart to start with and then i ride it and we have a giant balloon and then i go do you have a giant balloon giant balloon so step one uh sarah blows up the balloon okay [Music] use this air compressor it'll probably be a lot faster sarah and i get to work blowing up the balloon and it takes a long time a very long time okay human-sized balloon power car test take one all right sarah you got it yeah okay let it go nothing is happening it's not coming out fast enough and you're a bit too massive i don't think it's gonna work like this really yeah okay uh balloon powered car test two no fill i'll just take it what happened uh i don't think it worked the balloon popped phil are you okay this is why you wear protective eyewear uh yeah so that didn't work no no should we get another balloon i think we need something else okay well the air coming out of the balloon just what didn't have enough force so we need the air to come out with more force yeah do we get what a bigger a bigger balloon i don't think that's gonna work i don't think it's that i think we need something with compressed air oh like a scuba tank or a fire extinguisher something like that yeah that that's what we need okay sure well we can all right so i don't know if that's safe to do that so we'd have to build a like a cage or something i don't know if it's going to work on this all right well back back to the drawing board so what we should do is we should get them to find these tanks get the tanks and then we make like a frame out of aluminum or something okay that could work yeah they can hold the tank so they're safe and then what we should do is who was isaac newton he was a mathematician and probably number one on the list of top scientists of all time albert einstein said isaac newton was the smartest person that ever lived you've got to be special if einstein is calling you smart newton's three laws of motion was a huge idea but did you know newton also came up with the idea of gravity the famous story is that in 1666 isaac newton was sitting under an apple tree when he watched an apple fall and wondered why hey everyone i just invented gravity which was a big relief because up until then everyone was just floating around okay so it didn't happen like that he didn't invent gravity he gave a name to this invisible force and then described how it works not only did it make things fall down but it was the same force that kept the moon circling the earth and the earth circling the sun and he invented a new kind of math to explain how we now call it calculus see i told you he was smart he's very smart this is hydrophobic coating hydrophobic literally means afraid of water but it's not actually afraid of water the chemistry of a hydrophobic coating prevents water molecules from penetrating anything you spray it on you can get this stuff at the hardware store and if you want be science maximize you can get an adult and think of the coolest thing you could spray with hydrophobic coating i like to use things that do not go well when you put them in water like uh tissue yeah doesn't look great when it gets wet here's a tissue coated in hydrophobic coating huh weird or it works the same with a paper towel paper towel in water paper towel covered in hydrophobic coating [Music] stays dry or how about a dinner roll dinner rolls really don't like water see gross but a dinner roll colder than hydrophobic coating [Music] weird just don't eat it now it's time to max it out [Music] i have coated half of my lab coat in hydrophobic coating and the other half i have not hydrophobic coating regular lab coat half of me is wet and half of me is dry what's more half of my outfit ended up being wet and half dry because the lab coat was protecting my outfit from getting wet now it's time to max it out even more we have coated my entire outfit in hydrophobic spray my shirt my pants and my lab coat the pants have been taped to rubber boots so no water is getting in there and my shirt has been taped to my pants so no water's getting in there so here's the question can i get into the pool and out of the pool and stay dry let's find out in the pool out of the pool and i'm still mostly dry now here's what really happened i got into the pool and i realized i should have duct taped the pocket cause all the water went in there down into the rubber boots started filling up the rubber boots and now my entire leg is full of water because the hydrophobic coating isn't letting it come out so the hydrophobic coating isn't keeping the water out now it's keeping the water in let's take a closer look at newton's third law newton's third law for every action there is an equal and opposite reaction okay all right let's watch it back when the sign hits me i exert a force on the sign in the opposite direction that makes the sign stop moving it also exerts an equal force on me causing me to fly off in this direction now if i was to push this sign i'm not only pushing the sign this way but my feet are pushing against the ground in the opposite direction it's um well it's really easier to see if i'm not standing on the ground um no hold on okay huh oh okay so now that i'm hanging watch i push on the sign but when i exert force on the sign to make it go this way i go that way well actually it doesn't work as well because the sign isn't as heavy as i am so wait i have this over here this is a a barrel and it has stuff in it and it weighs as much as i do okay so watch if i push on the barrel like that i go away from it as much as it goes away from me so there you have it newton's newton's third no hold up newton's third law newton's third law okay go newton's third law for every action there is an equal and opposite reaction so using a giant balloon to push me on a cart uh didn't work what happened the plan now is to use the compressed gas cylinder just like a balloon these cylinders contain a lot of air if we get a cart and put a gas cylinder in a cage for safety on the back and open the valve the escaping air might have enough force to push me this is two cubic meters of air if we were to put it in a balloon the balloon would be this big but if we compress the air we can fit it all into one of these a steel tank this is what we're going to be using next for our air-powered car got it yep all right so sarah and i have been hard at work and we've built the air powered cart we can't call it a balloon powered card anymore because now we've got a compressed air tank so it's not a balloon that powers it exactly okay so i'm going to sit on here sarah's going to turn on the tank and i'm gonna go and before we do this we should say do not under any circumstances try this at home we are trained professionals you ready i'm ready okay high five first okay now we do it okay so before i turn the tank on make sure your feet are down and the brakes are on gotcha uh don't take them off till i say go you have got it all right ready okay [Music] oh [Music] yeah it worked uh yeah it did work but i feel i feel like it can work better you want to go faster i do want to go faster this reminds me of the rock car yeah we didn't have a big enough balloon and we need more force we need more force so should we get a bigger tank let's get more tanks more tanks more force you're gonna go faster forward newton's third law newton's third law high five all right let's do it all right [Music] [Applause] this this is newton's cradle and it's a really cool toy that demonstrates all kinds of laws of motion including newton's third law what you do is you pull this one ball out and when it hits these balls they exert force on that ball to make it stop moving but it exerts force on these balls which travels through the ball and makes this one on the end fly out like that now there's a lot going on here but you can really see how the force is equal that you put in and you get out if you use two balls i swing two balls up and two balls go out that side isn't that cool now it wouldn't be science max unless we maxed it out so come on okay this is one we built out of bowling balls bowling balls bowling balls instead of smaller balls and i think it's gonna work the same way let's find out you throw one out and and yeah it works the same okay now let's try it with two balls okay we're ready wait wait wait and two balls throw them out and two balls on that side all right so there you have it newton's third law for every action there is an equal and opposite reaction so our single pressurized tank created enough force to move me but not very fast the plan now is to do two things first we're going to triple the amount of thrust by using three tanks we're also going to use some pipes that lock into each other to give me an initial push these pipes slide together and when the air is turned on the pressure in the pipes will cause them to slide apart which will push me forward after that i use what's left in the tanks to keep going all right now it's time to max it out i've enlisted the help of a few more science max people thank you very much corey you'll see now we have three tanks of compressed gas and we've also got this nifty little contraption how does this work sarah all right so each tank is attached to a tube and you can see that each tube goes into this one main tube so when we turn them on pressure's gonna build up and we're gonna go forward with more force well that's great and reed is stacking cinder blocks thanks reid uh up so that will push uh the pipe will push against cinder blocks and then i'll go that way all right well are you guys ready i'm ready all right let's do it now again i have to say thank you cory i've got it this is something you definitely don't want to try at home we are all trained professionals we have a physics degree here we've got tv people that make sure that this is safe so uh watch it and enjoy but please don't try any of this at home okay i'm ready sarah count me down three two one [Laughter] that was awesome that was really awesome all right high fives high fives yeah yeah yeah yeah and it's raining now so it looks like we're gonna have to stop so thank you very much for joining us on science max experiments at large in our episode on newton's third law 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 science math experiments at large wait i can play mary had a little lamp it's working it's working newton's cradle at a bowling balls come on you know this one sing along [Music] come on i mean come on science [Music] [Laughter] [Applause] you
