Drake Anthony recreates a historical 17th-century experiment by vacuum-sealing mercury inside custom-blown glass flasks. By mechanically agitating the liquid metal within these evacuated containers, Drake explores the resulting triboelectric glow, experimenting with different noble gas backfills and alternative materials to enhance the light-emitting effect. See the video below:
