It means I can stay up here as long as I don't have velcro or pH, you're okay, friction, your turn, our floating disk worked so well that we decided to build another one, if we have two floating disks, then we can erase they use different types of friction to push them to along something that has low friction like a mop and something that has higher friction like a pole with rubber balls on the end. Rubber has high friction, which is why we make car tires and the treads on our shoes. no rubber, okay, we have a giant race track that we have set up, we have two low friction floating discs and I'm going to use the low friction dust mop version to power my floating disc and Helena, what do you have?

Get the high friction rubber ball to start its motors, get ready and go, and we're off. Remember that Helena and I are using very different methods to make our floating discs move. I'm using a low friction dust mop and Helena is using high friction. rubber balls, as you can see my low friction dust mop doesn't have enough friction with the floor for me to push off. Helena, on the other hand, has no problems. win J crosses yes and here we have our winner yes on that ending like he felt way behind there still stuck in the Second turn, way to go, Helena, okay, so what was the strategy?

How did it work well? While I was using those red balls, I had friction that helped me steer, you know what? I think we need a little more oomph to make it even work. Better if we had something to push us even harder definitely uh wait I have an idea wait I need your I need your help come on I'm at iFly Toronto indoor skydiving to talk to you about friction That's Mike, he's going to help me, okay? We think about what you're going to do when we pass the thing, unfortunately we can't hear what Phil is saying because there's too much wind, it seems like he's trying to tell us something about friction, uh, yeah, he's saying the friction of the air rushing towards us. the camera is enough to counteract the force of gravity, that's why it's able to float or swim or whatever it's doing now, it seems like it could be saying that even something like air can have a lot of friction if it goes fast enough and The air in this chamber goes fast, that's why we can't hear a word he says.

Well, he seems to be having fun, so how important is friction? Well, let's say I'm out driving car tires. I need friction to grip the road without it, my car wouldn't be able to turn at all, but that's nothing without friction, the bolt that holds the wheels on the car wouldn't work, in fact none of the bolts, screws or glue on the car would work. It worked and nothing would stop moving or stick to anything else, even trees would fly away with the slightest freeze. Friction is everywhere and without it nothing would work. Okay, floating disc race in the second round, this time we decided to have a little more oomph, so Helen I. and I'm going to use fire extinguishers now don't use fire extinguishers at home fire extinguishers have a very important purpose and it's not for this, but we have these specials, are you ready?

H oh yeah oh yeah okay here we go Russell so The racers start their engines, use fire extinguishers and give us a lot of push, but because the disks we ride on don't have any friction wherever we point, we keep moving in that direction, which which makes steering very difficult. Cars cling to the ground. road and it can take curves thanks to the friction of its wheels when you don't have friction it's like moving on a ring of ice oh no, I'm out, yeah, high five, yeah, high five, yeah, hey, wait, I missed it ended, I ran out of fire extinguisher in the end, huh, but I had to cheat a little, so one for you, one for me and all for friction or lack of friction or lack of friction.

Science. Max experiments in general. What do we do next? the biggest fire extinguishers, I think it's okay, see you next time. I know where we can get some. In fact, we can go if we go to the fire extinguisher store where we get these fire extinguishers. Get

science

. Max is a show where we do small experiments and make them big if you want to try these experiments yourself visit our website for instructions but not all of Max's

science

experiments are the type you should try at home this one yes this no try this don't try this big yes big no, I don't know how you could do this at home and remember, if you're ever unsure, ask an adult, thanks for watching, watching the science, Max experiments in general, carbon It is an atom that is the basic component, but we know it.

I beg him to hit me on the head with a friction sign that is more of an impact, not a friction. Actually, how can you keep destroying my life?
