Flying glass panes

Flying glass panes are an obstacle encountered in Checkpoint 10, Checkpoint 11, and Zen Mode. The glass flies towards you, becoming a dangerous hazard, it jumps towards you in Checkpoint 10 stage 3. In Checkpoint 11, the glass self-destruct. Zen Mode glass panes will always avoid you.

A trick is to use one ball (preferably the quintuple-ball) to hit one, and knock everything else out of the way. (Only works in Low Gravity)
