I think it's neat and I want somebody to explain this to me.

Silicon Ball.

The only finger that stays straight is the index.

Does that help you work it out? :)

It's the flat hand equivalent of the "pilf regnif" which is the backwards "finger flip." Learn how to do this http://www.contactjuggling.org/wiki/ind ... inger_Flip in either direction, get yourself a really frictiony ball, and then do the trick without rotating your wrist sideways, making sure to apply ample pressure between your middle finger, the ball, and the base of your pointer.

In addition, here's an old forum topic on this same move:

and here's an archived version of the broken link in that thread:

That looks kinda fake to me, but I'm stupid.
I know good isolations seem to defy gravity but that seems to defy isolation.... It's like the hand is isolated and the ball is manipulating the hand... Pulleys and mirrors! Nasty Tricksy False. And string. (magnets?)

If you watch the video very closely, you will notice that the middle finger curls down with and behind the ball pressing it against the index finger.

I'm tempted to callous up my fingers using sandpaper over a few weeks so I can do the finger roll with an acrylic... :(

Doesn't part of the illusion depend on using an opaque ball though? I don't mean to be discouraging, I think that the effect will be lost if people can see your other finger holding the ball. But perhaps there is a way to do it and I can't think of it.

I often do a similar trick with an Acrylic where the finger in the back really makes no difference. In the middle of a basic windshield-wiper, instead of going back into a cradle, I keep the ball touching my palm and grip it with my thumb, so it looks as though the ball is floating and/or attached beneath my hand. People rarely if ever notice the thumb!

When you do a thumb lift/push with a clear acrylic the lens effect makes your thumb invisible so I suppose the same principle applies here. Still not convinced by that video though - does it reverse halfway through?

It certainly looks like it reverses half way through - I've never been able to get it that smooth on the way "back up," but getting it back is certainly doable. Unless I'm mistaken, there's a very shaky early 1900s video of Cardini floating around out there where he does both the downward and upward motions.

Allmost all of those "old school" .GIF animations were designed to loop. That's what's happening there. Actually its a rewind then loop. I've tried it with a lacrosse ball. It's pretty hard but you can do it without too many tries, at least enough to know it's real. To make it look that good is another thing.
