Explain this one for me, Skillers.

I'm happy for you to go in to great detail.

It's quite simple in theory, but hard to completely grasp. The cotton reels are narrower in the centre, meaning they amplify the speed when moving to the floor.

He made a simpler one before;

Watch this video on Youtube.

As he moves the paper along, it causes a rotation of the cotton reel, and the outside rotates at the same time. As the outside wheel is bigger, it moves faster along the paper. The one in that video is exactly the same, just with a gearing concept involved.

O_o

that is amazing?!?!

that's actually pretty cool (considering it's physics )

Physics >> Law

Why?

Everyone everywhere obeys the Laws of Physics, unlike your silly little laws

They aren't rules.....more guidelines.

I'm not arguing physics rules aren't important as obviously they affect all of us But I don't find it particularly interesting, unless it's HL

And I follow every law rule tyvm....ok, most of them.......well MEH

Physics is awesome, and you can't deny it.

lies!

lol wynney is right. gravity for e.g. is a more of a guideline
Physics is pretty good. one of the only lessons i'm not bored in

Chemistry ftw, experiments were awesome. Physics experiments were good to though ^^.

Biology? Noob.

Chemistry has the best experiments, but is basically just cooking.

Well, physics has some interesting experiments, basically any that can make people say "that can't work" and you can bring out the calculations to pwn them.

Physics = Science
Chemistry = Cooking
Biology = Colouring in

Fact.

here here

lol ^^
