Yes, yes, that should’ve been candy with a “c.” But we like getting your attention so it was intentional. Moving on, pictured below are the glittery rocks from Krypton, the one single weakness of Superman. Of course it’s not real but if you wanna impress your geeky friends, learning how to prepare these edible rocks is a good idea.

Kryptonite Candy

Brainy gal and frequent Instructables user BrittLiv (real name Britt Michelsen) posted a recipe for homemade glow-in-the-dark kryptonite candy. It’s actually not that hard to prepare and simply required food coloring. Other ingredients are a generous amount of sugar, aluminum foil, a vitamin B2 pill, mint oil, and a candy thermometer.

 

BrittLiv’s original goal was to find a nice and safe fluorescent ingredient. This took some time since most such substances were too toxic for consumption. Here’s when she hit the jackpot:

 

So I had to find an other easy to get food grade chemical with a high melting point. My solution: Riboflavin, better known as vitamin B2 or additive E101. It can be found in most vitamin pills, is not toxic and fluorescents yellow under UV light (and even under direct light). The only set back is, that it is destroyed by exposure to light, but in our case it should matter because the process is pretty slow. Btw. that is the reason why you should buy your milk rather in opaque containers and not in glass bottles.

Get the whole recipe at BrittLiv’s Instructables page.
