Set the world aglow with peace, happiness, and good times! Make yummy candies that actually glow in the dark. Mold fun, glowing gummies and sweet, glowing ice cubes in groovy shapes. Then grow a batch of crystal rock candy and watch it glow. A small amount of a safe, natural ingredient — riboflavin, or vitamin B2 — causes these candies to glow under the included blacklight flashlight. Learn about the chemistry of glowing materials and pigments, the physics of light and electromagnetic waves, and more science behind these delicious treats. This kit includes all the food ingredients needed for a groovy good time!
