Glow-in-the-Dark Ice Cream Exists — And It’s Made Out of Jellyfish

Glow-in-the-dark ice cream exists — but that’s not even the weirdest part. Its main ingredient is jellyfish protein, which makes each lick brighter and more luminous.

Once the protein extracted from jellyfish reacts with the warm temperature of a tongue, the pH level of the tongue increases to a higher level, causing the ice cream to glow.
