Another trick involving Fork Catches & the Fork/Palm Stack which is very similar to The Twist, all three balls are held then two are thrown simultaneously & caught in different positions.
Juggle a Cascade & stop with two balls in a Fork/Palm Stack.
Holding all three balls, move the hand holding only one ball over the stack with the palm facing down so that all the balls are in a single column. In one movement flick both wrists back, the hand holding the stack needs to keep hold of the ball in the palm, while the ball held in the fork grip is thrown straight up. The hand held over the stack also throws straight up then flicks back down to Claw Catch the ball thrown from the other hand & then catch the other ball in a fork. This transfers the fork/palm stack from one hand to the other. To continue take the bottom hand & carry the ball it is holding from the bottom to the top of the stack & repeat on the other side.
Remember you only throw the top two balls of the three ball column at a time & you are swapping the fork/palm stack from side to side.
