Science Max | FRICTION PART 1 | Science Max Season1 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 art science facts today's episode is about friction how can i hang onto this rope without falling can we reduce it so we can slide around [Music] can we increase it so i can climb a wall ha-ha i did it can i use it to fly yep friction today on sciencemax experiments at large hey science maximize i uh slippery but that's okay because today we're talking about friction friction is a force that is everywhere and happens when any one thing rubs against any other thing we do lots of things to increase friction like uh like wear shoes with big treads on them and we can do things to reduce friction like the experiment we're doing today we're gonna build a hover disk and it's very easy you take some cardboard and cut it into a circle just like this then put a hole in the middle of the circle you might want an adult to help you with that and then take a plastic drink bottle cap like this i like the ones you use the ones that you get on sport bottles because they have a little nozzle that pops open or closed and then you glue it around the circle and you get this then you need a balloon so you blow up your balloon i know you know that step and then twist the balloon so it doesn't get away from you when it's nice and twisted you can stick it over the drink bottle cap like this and then untwist it and this is why i like to use the plastic drink bottle caps that come from sport bottles because you can open it when you want and when you do your disc rides on a cushion of air reducing the friction with the table and it's almost like it's sliding on ice you can also use cds if you want to do a different design just make sure you're using cds you never want to listen to again now if any of this is too fast don't worry you can always go to the science max website where we have all of the instructions and now it's time to max it out we're going to see if we can make a human-sized rideable low-friction hover disc i'm going to the ontario science center where hopefully i have an expert that can help me the door is stuck i think there's a little bit too much friction with the that's got it oh no this isn't the science center did i go back in time again oh uh it is the science center uh helena hi hey phil you're here to see the hubbard yes please all right come on right this way so i made one in the lab that uh works pretty great it's on cardboard and it has a balloon the one you have here works on the same principle yeah it does but you know what my friend russell has some ideas about making something like this but even bigger do you think we can make one big enough to ride maybe yeah all right well let's take a look at the one you have here oh i see right this one works the same as the one i made it's really hard to move the disc but if you add some air it floats like a dream there we go great so let's ride it whoa phil not this one the one upstairs so you can ride that one oh okay should we bring this one just thinking no that's it's a little heavy i think we can leave it there what if we need it for reference oh i'm sure we'll be okay it is pretty heavy yeah let's come on let's go russell's seating are you sure we won't need it positive okay but if we have to come back i get to say i told you okay all right hey ramona you change your hair yeah it's nice it's like doing this now but it used to be used but now it's yeah i like it you should give me the name of your guy because i wanted to hey oh hey how are you you ever think to yourself no matter what i do i can't seem to get anywhere i can't i can't get enough traction well you my friend needs some more friction which one of these two shoes has more friction hmm take a closer look huh huh right bam this one this one doesn't have a lot of treads it doesn't have a lot of friction but this one it's got metal spikes on the bottom this is called a cleat and the spikes are for helping you grip onto the grass when you're playing soccer or golf increasing its friction why do you think skis are smooth on the bottom come on look at that it's so smooth and and gliding my hand just i can barely even touch the surface it just slides right off it sort of gliding swoon they're smooth to help you glide across the snow reducing their friction why doesn't this box slide down this ramp friction this roller skate has wheels wheels reduce friction but when i push the roller skate how come it doesn't just keep rolling forever and ever and ever and ever and going all the way around the world and writing a memoir say it with me richard louder friction can't hear you friction a little too loud friction ease it back friction how can i hang on to this rope without falling friction how can i how can i jump down on the floor without falling over friction and now you know your friction your friction your friction come on oh oh oh ramona the friction sign is broken reset [Music] oh the plan is to take our small hover disc and make one big enough to ride so i'm off with helena to another part of the science center to meet russell who has some ideas on how we can do it okay russell hey hi i'm matt hey phil how you doing russell how are you doing phil so this is the hover disk this is our small hover disk yes how does it work well um obviously you sit on here air will go into here it gets vented through all these separate holes here so we get an airflow over the entire area hopefully this will work to pick something up all we need is air oh well that's easy because the the small one worked like this so um i'll just we just put the balloon on right i hope you go [Applause] okay so we put the balloon on uh hold on hold on larger balloon okay sorry sorry that's okay okay twist it so it doesn't uh oh he's losing his air all right what'd you get hold on you're great one slide upgrade okay here we go go it's not it doesn't feel way too it still feels pretty frictiony i think uh we might need something more than a balloon so what do we do well i think we need more consistent air going through here okay so not a balloon not a balloon something i don't know opposite to a vacuum cleaner opposite to a vacuum cleaner that would be an uh like a leaf blower like a leaf a leaf flooring high fiving yeah awesome idea so why don't we make a couple larger uh discs when we'll hook some leaf blowers to them and we'll see what happens definitely give it a go okay great carbon is an atom and is the basic building block of all life as we know it you me all plants all animals are carbon based life forms other things are made of carbon too diamonds are carbon coal is carbon even pencil lead isn't lead it's graphite which is carbon if you were to take all the carbon atoms in your body you could fill 9 000 pencils of course i kind of prefer my carbon where it is our low friction hover disk still had way too much friction one of the problems that russell mentioned is that the balloon just wasn't giving enough air but then helena had the idea of using a leaf blower instead the plan now is to make a leaf blower powered disk by starting with a big circle of wood cutting a hole in the wood where the air will come through and then covering the bottom with a tarp that has many holes cut out of it for the air to escape because leaf blowers are made to push lots of air hopefully they'll be enough for me to ride it [Music] well this is the business look at this it's amazing it's good right oh yeah i love the tube high volume of air through that yeah so yeah i think it's a dryer vent uh that we i just found it in the lab and then this of course is a leaf blower uh so i get on here and then helen if you want to turn it on yep so once we fire it up the air coming out from the bottom of the disc raises me up and i float on a cushion of air i can't control it because the friction between the disc and the floor is so low i end up floating wherever helena and russell push me [Music] [Music] it's like human air hockey [Music] wow that worked amazing not too much control though i have no control whatsoever yeah no but this is great so the so we have the no friction down pat uh i feel we need some way to actually move well something to push you along i was thinking as you're going like you need like a broom or something a broom okay yeah what if we do what if we do like something low friction like a broom and something high friction like that that we could really sort of stick on the ground yeah then we could build we could build two of them and we would have two discs and two ways of moving them are we gonna race and we can race yeah that's what we're gonna do [Music] you
