Science Max | Rocket Car | Season 1 Full Episode | Kids Science

have you ever done a science experiment 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 large 3 News 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 science max experiments at large greeting science maximize 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 or every action there is an equal and opposite reaction 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 well let's go over here so how do you build a balloon powered car well I suggest you be science maximized because there's 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 popped 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 there also makes it easier to blow up the balloon you can use any number of things even just 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 this car I used a shish kebab skewer and I stuck it inside a straw just like that and then I attached the lids to the shish kebab skewer so the lids and the shish kebab skewer are attached and they rotate in de 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 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 this one I made out of paper plates and this is a snorkel awesome this one is the rock part cuz there's a rock on it I've got a 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 banner waffles an ice cube tray this is why I make a whole bunch of different cars because I can race them Sunday Sunday Funday at all it's the balloon powered car winner-take-all awesome first up later washing the competition denominator feel the chill of the refrigerator and last but not least the regurgitator 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 gonna go to the Center for skills development and training and we're gonna use the science behind the small balloon powered car and we're gonna make it big that's science it's Newton's third law but 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 oh hi Sarah hi fella this is Sarah and she's got a master's degree in physics from McMaster University right and we're gonna be talking about Newton's third law look out duck sorry sorry there was a sign that kept coming in 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 cool okay so if you blow up the balloon what's gonna happen when you release it is the airs gonna push out with a certain force which in turn is gonna cause the car to move forward with the exact same force yeah works great so how come it doesn't work with my rock car 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 push forward but your rock is really heavy so you probably didn't see it really oh so a lighter car works better with the same amount of force well there you go Newton's third law what there is an equal and opposite reaction I'm really starting to dislike that sign so 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 in order to max out V 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 Sara blows up the balloon use this air compressor toy probably a lot faster Sarah and I get to work blowing up the balloon and it takes a long time the very long time okay human size balloon power car test take one right Sarah you got it yeah it's not coming out fast enough and you're a bit too massive I mean he's gonna work like this really okay balloon powered car test - no fill I'll just take it uh it worked the balloon popped so okay this is why you wear protective eyewear uh yeah so that didn't work no no should we get another balloon oh 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 it what a bigger 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 or like a scuba tank or a fire extinguisher stomach yeah that's what we need okay sure well we can alright so I don't know if that's safe to do that so we'd have to build a like a cage or yeah I don't know if it's gonna work on this all right well back back to the drawing board so what we should do is we should get up to find these tanks and get the tanks and then we make like a frame out of aluminum or something okay that can 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 persons 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 describe how it works not only did it make things fall down but it was the same force they 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 besides 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 tissue yeah doesn't look great when it gets wet here's a tissue coated and hydrophobic coating huh weird or it works the same with a paper towel paper towel in water paper towel covered in hydrophobic coating stays dry or how about I didn't roll dinner rolls really don't like water see gross but it's in a row coated in hydrophobic coating weird just don't eat it now it's time to Max it up 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 Mia's way and half of me is Drive 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 robber boots so no water's getting in there and my shirt has been taped in 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 now here's what really happened I got you're gonna pool and I realized I should have duct taped the pocket cuz all the water went in there now names in the rubber boots started filling up the rubber boots and now my entire leg is full of water because the hydrophobic coating is Atlanta you come out so the hydrophobic coating isn't keeping the water out now it's keeping the water again let's take a closer look at Newton's third law for every action there is an equal and opposite reaction alright 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 how is 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 No hold on okay 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's it doesn't work as well because the sign isn't as heavy as I am so wait I have this over here a barrel 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 third law okay go Newton's third law or every action there is an equal and opposite reaction so using a giant balloon to push me on a cart 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 gonna 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 fired card anymore because now we've got a compressed air tank so it's not a balloon that powers it exactly okay so I've missed it on here Sarah's gonna 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 off got you we'll take them off till I say go you have got it all right ready okay yeah yeah it did work but I feel I feel like I could work better you wanna go faster I do want to go faster this reminds me of the rock car yeah we didn't have a big enough balloon you 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 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 play this one ball out and when it hits these balls they exert force on that fault to make it stop moving but it exerts force on these balls which travels through the ball and makes this one in 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 up that side in that cool now I wouldn't be signed to 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 yeah it works the same okay now let's try it with you boss okay we ready wait wait wait and two balls throw them out and two balls on that side all right 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 alright so each tank is attached to and you can see that each two goes into this one main tube so when we turn them on pressures gonna build that and we're gonna go forward with more force well that's great and Reed is stacking cinder blocks thanks Reed up so that will push the pipe will push against cinder blocks and then I'll go that way alright well are you guys ready I'm ready alright let's do it now again I have to say Thank You Corey 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 watch it and enjoy but please don't try any of this at home okay I'm ready Sarah count me down three two yeah that was awesome that was really awesome all right high fives high fives 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 math experiments at large our episode on Newton's third law science max is a show or 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 max experiments at large wait I can play mary had a little lamb it's working Newton's Cradle at a bowling balls come on you know this one
