Make a slime that changes color from white to pink-orange in strong ultraviolet light, like direct sunlight. Ooze Labs are fun and simple science experiments that come in a big plastic test tube that contains a simple science experiment to create. They come assorted in four different types picked at random: thermocolor slime, sunshine slime, glow-in-the-dark slime, and magnetic slime. Each sold separately.
