Glow in the Dark Ice Cream

Each scoop of this ice cream is priced at £140 or about $225. That’s more expensive than most of the tubs you can find in your local grocery’s freezers, but for good reason: this ice cream glows in the dark. It’s made using the same protein that makes jellyfish glow by British foodie Charlie Francis, who’s the founder of the Lick Me I’m Delicious ice cream company.

Charlie explains: “It’s glow-in-the-dark jellyfish ice cream using calcium-activated proteins that react when they are agitated, or to put it a non sciencey way, it glows when you lick it.”

But why does it glow? As Charlie explains further, the act of licking warms up the protein in the ice cream, causing an increase in its pH level, which produces the glow. Charlie adds: “Is it safe to eat? Well I tried some and I don’t seem to be glowing anywhere, so we’ll go with a yes for now. We’ve also made a non-jellyfish version using quinine from tonic to make a glow in the UV dark gin and tonic sorbet which is pretty neat.”
