Glow in the Dark Slime

Here's a fun Halloween chemistry project for you. Make some glowing slime! This recipe is for a clear slime that glows in the dark after you expose it to light. The main ingredients are glue gel, borax, and glow in the dark (phosphorescent) paint or powder. There are several glue gels that will work. Elmers™ has a pale blue gel, supposedly there is a clear gel, and I have seen blue and red gels that come with glitter and stars in them. Any of these will work. If you can only find white glue, you can use the classic slime recipe, except add the glowing ingredient to the glue solution before you mix it with the borax solution. Glow-in-the-dark slime is fun to make, plus you can use it as part of a discussion about polymers and phosphorescence. You can get borax at most stores, sold on the laundry or clear aisle. The glue is sold with school and office supplies. Since the average person isn't going to order zinc sulfide, I'd recommend using glowing paint powder or liquid paint from a craft or hobby store.
