And it's $235 a scoop! The ice cream was created by UK company Lick Me I'm Delicious in time for Halloween, and was inspired by glowing jellyfish. It's made using a synthetic, calcium-activated version of the protein that makes jellyfish luminescent, and lights up when you lick it. However, inventor Charlie Harry Francis didn't offer much reassurance on whether the product was safe to eat, writing on his blog: "Well I tried some and I don't seem to be glowing anywhere, so we'll go with a yes for now."
