Glowing ice-cream made with jellyfish proteins

The Lick Me I'm Delicious ice-cream company has created a limited run of glowing ice-cream that uses jellyfish proteins in its recipe; when they're licked, the agitation causes them to glow. A scoop costs £140.

But what on earth is it??? 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. It's also pretty insanely expensive stuff, we worked out each scoop is coming out at around £140, dam those big bucks jellyfish. 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 and can be ordered from all good Lick Me I'm Delicious event contraptions.
