Glow in the dark Slime recipe

With the little guys Monsters University birthday party coming up this weekend we’ve been busy gathering all of our favorite monster party ideas for the big day. After watching the slime monster fall through the sewer grate in Monsters Inc I had the idea of making glow in the dark slime with the kids. The kids and I have been making slime for years but this was our first time trying glow in the dark slime..needless to say the kids LOVED it! We plan to make a few more batches later this week to give as party favors with one large googly eye in the center..fun, right?

-makes about 2 cups

2 Elmer’s white glue bottles (4oz)
3-4 tablespoons glow in the dark paint
Neon food coloring
1 teaspoon borax
1/2 cup warm water


Step one: Pour the white Elmer’s glue into a bowl. Fill the empty bottles with warm water, place the lids back on and shake the bottles (this will help remove any remaining glue inside the bottle and make it easy to measure your water). Pour the watery glue into the bowl and mix with a spoon.
Step two: At this point you want to add food coloring to your glue (I used a neon green from McCormick).

Step three: Stir in the glow in the dark paint into your glue mixture.

Step four: In a small bowl mix 1/2 cup of warm water with 1 teaspoon of Borax (the warm water will help dissolve the borax).

Step five: Mix the borax water and glue mixture together with a spoon, but but don’t be afraid to use your hands to fully mix the two together.

The special ingredient that makes the glue turn into slime is the borax. Play around with the amount to get the perfect consistency, if you prefer a runny slime use less borax. Also, when you first began mixing the glue and borax water the slime will be VERY runny and a weird texture, don’t freak out! The more you play with it the better the consistency will turn out.

In case you’re wondering I tried this recipe with two different glow in the dark paints. We preferred the one on the right from Americana but the Glo-It from DecoArt also worked well with smaller batches.

We also tried this recipe with glitter glue which my daughter loved! You can see the glitter specks in the glow in the dark picture below. The only downside to using the glow in the dark paint with the glitter glue is that it made the glue a milky color instead of being see-through like it normally is in the bottle.

My kids love that they can shape it with their hands but if left alone it looks like spilled slime. Speaking of slime do you guys remember Nickelodeon’s slime? I may have been born in the 80s but I’m a 90s kid all the way! I always wanted to go on the Nickelodeon shows and get slimed, it always looked like fun! :)
