Space Juggling - Neatorama

How does juggling work in space? The main thing you have to remember is that a ball thrown in the absence of gravity will not fall- it just goes in a straight line until something stops it. Physicist Adam Dipert is the Space Juggler. He explains how the idea came about.

It's interesting but I suspect you'd get a different effect and perhaps it would be more engaging. I think maybe if he was spinning in the first video the juggling would look more impressive.

They're lying. The rainbows are a sign of unicorn meat being slipped into our food supply.

How is this an explanation when there is no information as to the origin of some diffracting medium?

I was going to let this pass, but since E Cheung asked the right question, I guess I need to answer him.

The effect likely comes not from diffraction as seen on a CD, but from thin film wave interference. The Naked Scientist (link below) has the best, quick description that I could find. Google "Oil Rainbow Effect" to get more information.
