A Demonstration of How Couscous Can Be Formed Into Beautiful Patterns Using Wave Vibrations
by Glen Tickle from Laughing Squid on (#161BJ)

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.
