3b Ratchet
From Contact juggling
It is essentially the same move as the propeller. Place the balls on the palm of your right hand, two on bottom, one on top, your left hand should be holding the formation from the top. Now start spinning the balls like in a regular propeller, except now rotate your hands so that the left one is on bottom, right one on top. This also makes a rather interesting 4-ball transfer from one hand to the other. it's a three ball iso. but it also works excellently with a 4-ball stack.
