Noisy Jelly.

This is really fascinating! Noisy Jelly is the creation of Raphael Pluvinage and Marianne Cauvard. The player creates his or her own musical instruments with a simple chemistry set. Mix powder with water with a dye/ instrument of your choice, wait ten minutes, and Voila! Squishy instruments at your fingertips. Just pop ‘em on the sound board and play. The audio sound produced is dictated by the variations of shape, salt concentration, distance, and the pressure of fingertips. (via Booooooom!)
