absolutely brilliant!

Differential rotation! That is perfect. =20

I am on my way to Bed, Bath and Beyond.

Thanks, man. - jz

Howdy Tapplers!

I was at the dreaded Bed, Bath and Beyond with my wife and came across a
bouncy ball they called a "glitter ball", its basically a bouncy ball =
filled
with water (I think it's water anyways) and glitter. When you bounce it, =
the
glitter swirls around. Ok, now for what I thought was the cool part. I =
wound
up buying quite a few of them and I'm using them to pass around and show
differential rotation. This was always a really difficult concept for my
students to grasp, but with the aid of the glitter ball they can really =
see
differential rotation at work.

I am also planning on using them to show newton's first because once in
motion, you can twist the ball around (not too vigorously) and the =
glitter
will not change direction.

Just a cheap demo tool I thought you guys might like to play with.

Anyone else have any idea of what else I could use it for? I was =
thinking of
dropping a ping pong ball on it for momentum too....
