Champagne glass (or 45P22.1) is a period-22 billiard table oscillator discovered by Dean Hickerson using his drifter search program on April 19, 1997, being found only two days after 168P22.1. In terms of its 45 cells, it is the fourth smallest known non-trivial period 22 oscillator, behind Jason's p22 with only 36 cells, a p22 honey farm hassler (40 cells) and a p22 pi-heptomino hassler (42 cells).

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.
