There are only a few acceptable reasons to lick a jellyfish, but licking a fluorescent "jellyfish" ice cream cone? Now that's something you need to do. British ice cream maverick Charlie Francis recently unveiled a glow-in-the-dark ice cream that harnesses its magic from chemically recreated jellyfish protein, and it'll only cost you about $225 a scoop. This frozen dairy witch-ery got started when Francis read a research paper on jellyfish and got to brainstorming. He worked with some scientists in China -- who were apparently dying to get some jellyfish protein in their waffle cones -- to bring this monster to life. The final product reacts to your tongue, upping the protein's pH level with each lick. Basically what this means is the more ice cream you eat, the more it glows.
