Columns is an easy pattern that’s great for putting some variation into your routine, and it also has some applications in timing and comedic juggling. The most basic variation of columns is as follows. Start by juggling two balls in your right hand, but make your throws all go straight up, creating two ‘columns’ of balls being thrown.
Now, with the ball in your left hand, make the same straight throw, but time it with the ball furthest to the right in the right hand. This creates an effect where the outside columns are synchronized, and the middle ball is always in an opposite position.
The real fun of columns comes in the variations. The two rightmost balls could be synchronized, leaving the left alon, or all balls can be thrown in sequence for an equalizer effect (personal favorite).
