Any kid knows how to produce an entire foley library worth of gross sound effects from a bowl of jelly, but Raphaël Pluvinage and Marianne Cauvard’s Noisy Jelly kit produces more pleasing sounds using gelatinous shapes and a special playing board.
The kit includes food colouring and agar powder, which lets the performer mix up a tinted jelly concoction in a mould of various shapes. After 10 minutes the jelly creations are solid enough to be removed and placed on a special playing board covered in capacitive sensors.
When the jelly shapes are poked and prodded with a finger, they each produce a unique sound based on their shape, their size, the strength of the touch, and the concentration of salt in the mixture, which affects how it conducts the electrical charge from the performer. There’s probably a joke in here about playing with your food, but those agar creations don’t actually seem very appetising. [Pluvinage via designboom]
