Columns is a juggling trick where the balls are thrown upwards without any sideways motion. The simplest version involves having three balls, with two going up simultaneously on either side, followed by one going up in the middle. The effect of the trick is that the balls are not crossing at any point, so your hands have to move a lot quicker and further than in a regular pattern.

The trick can be extended to any number of balls (within reason!) and can be varied by doing synchronous or a-synchronous throws.
