How to Make Glow in the Dark Halloween Monster Slime

The reason I’m so glad to see more kids playing with toys like slime and other homemade crafts is because of how incredibly rampant technology use is nowadays. It seems like everytime I leave my house I see a kid somewhere playing with an iPad or a smartphone. It’s especially alarming when you stop to consider that numerous studies are finding that smartphone use may be contributing to a serious decline in cognitive functioning. (1)

With that in mind, I’ve definitely been steering my own kids towards more crafts and DIY projects to keep them busy and away from technology as much as possible. One of our favorite things to do together as a family lately has been to make our own homemade slime. Today I’ll be sharing a recipe that we’ve been making quite often lately. It will show you how to make magical glow in the dark slime.

In order to actually make the slime, you’ll first need to mix together ½ teaspoon of borax with ½ cup of water in a glass or jar to make the activator. When you mix this liquid solution in with the glue that you’ll also be using, it will form the slime-like consistency that you’re looking for. After mixing the borax and water together, set it to the side for now.

Next, grab a bowl and add ½ cup of clear school glue into it and then mix in the glow in the dark neon paint. Once you’ve combined the two ingredients, you can gradually add in your borax activator, ½ teaspoon at a time, stirring slowly as you pour it in. Eventually the mixture will form into a slime that gets harder and harder to mix.

When that happens, you can take the slime out and start to knead and stretch it — if you find it too sticky to hold, you can simply wear a pair of gloves. Keep kneading and stretching your slime until it stops sticking to your hands. Whenever I make this slime with my kids, I usually help them with the mixing of the ingredients and then let them take over for the kneading and stretching duties — they always have so much fun doing it.

If you hold your slime under any kind of black light, it will “glow” quite brightly indeed. My kids always say that it reminds them of those glow in the dark mini golf places. In fact, the last time I took them there, they made sure to bring along some of this glow in the dark slime. It was such a fun day!
