British singer Imogen Heap shows off her vocal skills and the science of sound in this short home video clip. She pours some table salt onto a small drum and sings it into shapes, creating different patterns by changing her pitch. These “Chladni” patterns are produced when sound waves at the right pitch reinforce natural vibration frequencies in the drum, causing the salt to gather.
