Addressing a truly niche market — affluent people coping during a blackout — British inventor of edibles Charlie Francis has created a glow-in-the-dark ice cream using synthesized jellyfish proteins. It's $220 a scoop. Francis is the owner of Lick Me I'm Delicious, which specializes in exotic ice cream flavors. They've tried these flavors too: roast beef, salted whiskey caramels, rhubarb chocolate macaroons, raspberry mojito, and cheddar cheese.
