You can now play a piano made of jelly, thanks to a new game that lets you cook up and mould your own designer instruments. Created by students Raphaël Pluvinage and Marianne Cauvard from the French National Design Institute (ENSCI) in Paris, the edible shapes could be used in offbeat performances or as a playful way to teach the basics of physics, chemistry or electronics.

Water is then added to the mixture before it's poured into a mould. Ten minutes later, a hardened shape is ready to be placed on a game board that detects differences in electrical conductivity, in a similar way to how a touchscreen responds to a finger
