Food inventor Charlie Harry Francis of Lick Me I'm Delicious came up with this never-before-seen creation that is, in fact, edible. So what's the secret behind the glow? It's caused by "calcium activated proteins that react when they are agitated," AKA the stuff that makes jellyfish glow. Basically, if you lick the ice cream, it starts to radiate light!
Unfortunately, the ice cream would set you back $225 per scoop, because apparently jellyfish glow is expensive. Francis achieved the same result another way though, using "quinine from tonic to make a glow in the UV dark gin and tonic sorbet," which we can only assume is a bit more affordable.
