Box (2x,4)(4,2x)
The box is a trick in which two balls, one in each hand, are thrown straight up in an alternating pattern. A third ball is shifted between the two hands while the ball for that hand is in the air. To learn this trick you must first master the shower in both directions (left to right, right to left) Then you learn how to switch between the two pretty well. From that start doing three throws in one direction then switch to the other and do the same. Once you have that down decrease the number from two to three and eventualy go down to one and that is esentialy the trick. Make sure that the two outside balls go straight up and down or else the trick is doomed.
