Noisy Jelly. No, that’s not a typo, I do actually mean Noisy Jelly.
French interaction designers Raphaël Pluvinage and Marianne Cauvard were obviously bored with simply eating their jelly and wanted to stimulate more than just their taste buds. Cue Noisy Jelly – an interactive and tactile musical instrument which you can make yourself… out of jelly.
The game board itself is in fact a capacitive sensing device with the differences in the jelly shape and salt concentration, that you create yourself with water and agar powder, affecting the sound.
You can also influence the final audible output with the strength of contact and manipulation you place on it with your hand and fingers.
