The video will possibly be edited slightly, and converted slightly to reduce the size of the file. When submitting a move, don't forget to include a short explanation of what's going on in it. Also, include your contactjuggling.org username so we can say who submitted the move. For learning palmspinning you need at least two, but for most moves you want at least three really smooth balls. That smoothness is as far as I know only to be found in acrylics and billiard balls.
Acrylics are expensive.
As you're probably not sure that this hobby is the one for you, you'll probably don't want to spent the money on something that you might lay aside when you realize the time it's gonna cost you to learn this. Billiard balls, although they are somewhat on the small size are then good enough to learn with. Chico is currently working on another palmspinning guide, but that is not yet finished. A rubber doggy ball or croquet ball is good. First of all, try Marco's Workshop, which has graphical instruction on how to learn the basic moves.
