Homemade slime is an all time favorite around here. Whether you call it slime, gak, or putty this homemade glow in the dark slime recipe is a fun activity for kids that will keep them occupied for hours!

Glow in the Dark Slime

Glow in the dark crafts are fun for kids and great for late night parties. One of our favorite slime recipes is this Glow in the Dark Slime! The slime is activated by light then glows in the dark. We have been making this slime for years and have used it as a party favor many times. If you’re hosting a glow in the dark party be sure to check out these amazing GLOW IN THE DARK IDEAS!

There are many ways to make slime and I’m going to share a couple different recipes you can try with kids.Slime recipes can be made with or without borax. If you prefer a no-borax slime recipe, contact lens solution is a great alternative. To make this recipe you will need glue, borax or contact lens solution, glow in the dark paint, and neon green food coloring. The original slime recipe is below and the updated no-borax recipe is further down the post.

How to make glow in the dark slime

Our original slime recipe:

  • 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.
  • At this point you want to add food coloring to your glue (I used a neon green from McCormick).
  • Stir in the glow in the dark paint into your glue mixture.
  • In a small bowl mix 1/2 cup of warm water with 1 teaspoon of Borax (the warm water will help dissolve the borax).
  • 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.

No-Borax Glow in the Dark Slime Recipe

How to make glow in the dark slime without borax

  • Pour glue in a bowl.
  • Add baking soda and glow in the dark powder; stir until well combined.
  • Pour in contact lens solution and stir until slime begins to form. Remove from bowl and work the slime with your hands until the consistency is right. Add a couple drops of contact lens solution, if needed.

In case you’re wondering we tried the original 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.

Glow in the dark slime tips

  • Slime is too sticky – first, make sure you have knead the slime enough with your hands. After a few minutes if the slime is still too sticky then you can add a couple drops of contact lens solution until the consistency is right.
  • How to store slime – always store slime in an airtight container. This can be a plastic bag or container with a lid.
  • Should I use glow in the dark glue or powder – we used glow in the dark glue for years and it works great. Recently, we discovered glow in the dark powder and this has been our go-to glowing slime ingredient. The glow is BRIGHT and is easy to mix in with the baking soda.

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! :)

I am making this at my son’s Halloween party. I am trying to figure out how much of each ingredient I need if I want to give about a half cup of slime to each of the 24 children. Thanks!


I just made this for my toddlers monsters inc party. Found on Pinterest. Love it! Gave my toddlers some to sample. They were enthralled. Today is Friday, party is Sunday. Giving it as favors in small airtight containers. Any idea how long it will keep like this? It’ll still be good when Kurds take it home, right? Thanks for sharing!

I too am wondering how long this will keep? I am hosting a halloween party, on a wednesday, but my schedule is quite busy with all the other prep. I suppose I could made a big batch and just wait to split it up until the day before.

Ami, as long as it’s in a closed container you won’t have a problem. It can last for months if the container is sealed. I hope you have a fun Halloween party!

Made this up yesterday with my grandkids, ages 7 & 3. So easy to do, each got a turn at mixing up their own batch! They absolutely love it and played with it non-stop for almost 3 hours just sitting around the kitchen table! Will certainly make more.

Is this something that can be molded with hands and it retain it’s shaped or is this one that will stick to hands and be runny? I’m only wondering because it think I want to make it if it so something less runny and something he can take out again and again.

Great recipe, but I’m not impressed with Martha Stewart’s glow in the dark paint. Or I’m not using enough. Next time I will use the Americana brand and order it online since Michael’s was out.

Also, just thought of another question. Could I add the glow in the dark paint in after the slime has already been made?

Do you have to use Neon Food Coloring?

Wow this is such a great idea. I’ll defiantly have to put some of this in my Halloween feel box. I just know that everyone at the party will love it too.
