There are some creations that are downright weird but somehow equally cool, and and glow-in-dark ice cream—created using jellyfish protein—is one of them.

Charlie Francis, founder of Britain-based company, “Lick Me, I’m Delicious” is the person behind the glow-in-the-dark ice cream.

After Francis read a study on jellyfish, he worked with a scientist in China to synthesise the luminescence protein from jellyfish.

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,” their blog reads.

And the ice-cream isn’t cheap, either. It comes in at around $225 for 140 pounds. Still, Francis tells Mashable that it sells pretty well, despite the cost.

And as far as the safety of eating the ice-cream, he writes in his post, “I tried some and I don’t seem to be glowing anywhere, so we’ll go with a yes for now.” It doesn’t seem as assuring, but for the skeptical, he has a non-jellyfish version made “using quinine from tonic to make a glow in the UV dark gin and tonic sorbet.”

If you think this is strange, what he has in store next is even more alarming. The inventor tells the LA Times that he wants to create invisible ice-cream, and is looking for scientists or magicians who can help.
