A COLOUR CHANGING slime!! Choose between a pink, purple, yellow and blue slime. These slimes are made with photochromic pigment. This pigment changes colour when exposed to UV rays, so just hold your slime out in the sun and watch the magic happen! Your slime will come with a dash of pigment on top that you can mix into the slime yourself. This slime is unscented. Please note that your slime will appear white when it is not exposed to any UV rays.
IMPORTANT: All our slimes are made with a borax based activator. Slime is not edible. Recommended for ages 8 and up.
