At first glance, it’s hard to tell what this small thing is. It glows in the dark and could resemble something that’s out of this world. But, it’s actually a lollipop that uses the phenomena of fluorescence to create a playful and edible treat! Combing candy, fun, and science, a simple-but-crucial ingredient allows this lollipop to absorb energy from ultraviolet (UV) light.
Madrid-based site Verde Matcha made the sweet treat using sugar, tonic water, corn syrup, lemon juice, and a vanilla pod. The water contains a substance called quinine that produces a bright blue color when it’s under UV light. So, to fully enjoy the immediately-brightening effect of the lollipop, you’ll need to have a black light handy.
Tonic water is safe to eat and drink, so if you’re interested in making your own fluorescent pops, check out Verde Matcha’s recipe. We’d imagine that this would be a lot of fun at a high-energy dance party in lieu of your standard glow stick. Not only can you wave it around like one, but you lick it, too!
