Curious about why we use saline and baking soda to make our slime? All the details are here, but in a nutshell, we live in Canada where we can’t access liquid starch and our government has advised us to limit the use of borax powder around kids. I also have health issues that are aggravated by borax powder. This recipe is super easy and makes insanely stretchy slime that has a wonderful texture.

How to Make Glow In The Dark Slime

Add one bottle of glue to your bowl. How much glue you use is extremely forgiving. We buy our glue in bulk and use a nice sized “gloop” of glue. It’s probably around 4 to 6 oz. Add a 1/4 teaspoon of baking soda. Mix well. Add 4 to 6 tablespoons of glow in the dark paint. Mix well.

Add a squirt of the buffered saline. Mix well. Add another squirt. Continue mixing. Once it starts to get stringy and pull together, start adding only a couple of drops of saline, and mixing well. Once it is pulling together, add some saline to your hands and start mixing and kneading it with your hands.

If you over do the saline it will become stiff and prone to breaking. Slow and steady with the saline with lots of mixing is important!

Once you have a nice stretchy slime you can add some accessories. We found some fun spiders and eyeballs.

Now head into a dark room. Your slime should start glowing immediately. To really turn up the glow fun use a blacklight (also known as a UV light), this will really help your slime GLOW!

For an extra fun twist, dress the kids in some reflective clothing, neon or white for extra glow fun under the black light.

This slime was extra fluffy due to the amount of paint we added. It made for a really cool texture that was a lot of fun to play with. The kids can’t wait to set this one up at a Halloween party!
