The Coolest Glow-in-the-Dark Halloween Slime

With Halloween around the corner, I wanted to share a recipe for the coolest glow-in-the-dark slime. Instead of adding glow-in-the-dark paint to the basic recipe, I wanted to add glow in the dark objects to clear slime to see what would happen. I found candy skulls and bones sprinkles (the kind used to decorate cakes) and spray painted them with glow-in-the-dark paint. Once they dried, I added them to the slime, exposed the slime to bright light and the result was exactly what I was hoping for.

This is a fun craft for parties if you can paint the skulls and bones ahead of time. It wasn’t time-consuming to spray paint the candy sprinkles, it took all of 5 minutes, the most time-consuming part was waiting for the paint to dry and reapplying a second coat. The kids will get a kick out of turning off the lights and seeing all the skulls and bones glow through this clear slime.

Glow-in-the-Dark Halloween Slime


9 oz bottle of Elmer’s Washable Clear glue

1 teaspoon of baking soda

1 tablespoon of saline solution (I used a generic contact lens solution)

1 container of Wilson’s Sprinkles candy skulls and bones

1 can of glow in the dark spray paint


The Coolest Glow-in-the-Dark Halloween Slime

To make:

In a well ventilated area (read the spray can for instructions) spread the skulls and bones on a piece of newspaper (or similar) and lightly spray them with the glow in the dark paint. Let it dry and coat them again one or two more times. Glow in the dark paint is most effective with several coats. Once the skull and bones have completely dried, you can make the slime.

To make the slime, pour the entire contents of the glue into a medium-size glass of plastic bowl. I’m not a slime expert by any means, but I read that metal bowls and spoons should not be used because it could affect the chemical reaction. Add one teaspoon of baking soda. Stir until thoroughly combined. Add one tablespoon of saline solution and stir. Within a few seconds, you will see the slime begin to form. As you are stirring, it will eventually form into a ball. You can add the skulls and bones and glitter and mix it all together until thoroughly incorporated.

And here’s the thing about slime, you don’t really “do” anything with it except play with it. It’s a lot of fun to make and to squeeze in your hands – I actually found it very therapeutic! To store the slime, you can put it in a ziplock bag or an airtight container. It definitely becomes more dense over time and loses the really stretchy consistency. But, now you know the recipe you can make some more!

A few warnings: it will stick to clothes and hair, so push back sleeves and put an apron on your kids. If you add food coloring, it will stain your hands and nails unless you wear gloves. I don’t wear gloves because I’ve found that the food coloring will wash away after a few good washings with soap and water.
