Champagne glass (or 45P22.1) is a period 22 billiard table oscillator discovered by Dean Hickerson on April 19, 1997,[1] being found only two days after 168P22.1. In terms of its 45 cells, it is the second smallest known non-trivial period 22 oscillator, behind 36P22 with only 36 cells.[2] It contains a bookend acting as an induction coil.

Whereas its rotor reflects itself after half a period, saving two live cells by using a bookend rather than a house as an induction coil breaks the overall symmetry of the figure.
