Everyone knows what food coloring does to food – so you can easily imagine what it would do to slime. Food color makes an easy addition to slime, a couple drops and some mixing and you’re done. You can play with the amount of food coloring added in order to achieve a lighter or darker effect. The downside of food coloring is that there are limited colors available and the resulting color of your slime may not be unique.
Yes, we already discussed pigment powders. But glow in the dark pigments deserve its own category. Party loving and fun loving slimers alike will definitely find these enticing. These can be found in powder form across many different colors. First, shine a light onto the pigment-infused slime. This energizes the crystals of the pigment and stores up energy. Then, you can cloak the slime in darkness and the phosphors in the pigment will slowly emit the stored energy with a stunning glow. Don’t forget the first step, or you’ll be wondering why the glow-in-the-dark is not working.
