A Demonstration of How Couscous Can Be Formed Into Beautiful Patterns Using Wave Vibrations

Science presenter Steve Mould gave a demonstration on how wave vibrations can be used to arrange couscous into beautiful patterns. Mould drew a bow across the edges of a metal plate to vibrate its surface in different patterns.

The patterns are called Chladni figures, and are named after German physicist Ernst Chladni who discovered them in the 18th century.
