Created by Charlie Harry Francis from Lick Me Delicious, England, this ice-cream, which is made of jellyfish protein, glows in the dark when licked.
Francis's creation starts to glow upon the tongue's contact with the treat. The trick? He makes it with the fluorescent proteins found in jellyfish. The proteins interact with the tongue's pH levels so the ice cream increases its luminescence the more it is licked. And jellyfish proteins don't come cheap - a single scoop costs about $225.
