DIY Galaxy Slime
Today I have an absolutely awesome DIY galaxy slime recipe to share with you.
While you may print out the instructions and buy the supplies for with your kids in mind, you are going to want in on the action too. It is just so beautiful!
How to Make Galaxy Slime
Since this slime is a combination of multiple colors of slime and glitter, you will notice that you basically need to make 3 seperate slimes, then combine them together at the end.
Start by gathering all the ingredients and supplies that you will need to make your slime.
Galaxy Slime Ingredients
- 1 (6 oz) bottle black glitter glue
- 10 oz clear glue, divided
- 1½ cup water, divided
- 1½ tsp baking soda, divided
- 3 tbsp saline contact solution, divided
- purple food coloring
- teal food coloring
- pink, purple, gold, and teal glitter
- star confetti (optional)
You will also need 3 medium-size bowls/containers as well as 3 spoons/spatulas to use to mix each color of slime.
Black glittery slime is up first.
Combine the bottle og black glitter glue, 1/2 a cup of water, and 1/2 a tsp of baking soda. Stir well to combine.
Add 1 tbsp saline solution and mix. You will see the slime instantly begin to form.
It will be super sticky but as you continue to mix and then knead the slime with your hands. Continue to knead until it is no longer sticky, then set aside while you move on to the next color.
Once the black slime is complete, it is time to start making the purple glittery slime.
Combine a bottle of clear glue, 1/2 a cup of water, purple food coloring, and pink and purple glitter. Stir well to combine.
Add more food coloring as necessary to reach the desired shade of purple.
Don’t be shy when it comes to adding glitter. You really want to dump that glitter on in there, as you can see we did in the image above.
Add 1/2 baking soda and stir well.
Now add 1 tbsp saline solution, mixing well and then kneading with your hands until it is now longer sticky.
Set the purple slime aside while you prepare the last color slime — teal.
Simply repeat the process you used to make the purple slime using the teal food coloring and teal and gold glitters.
Once you have made all 3 colors of slime, twist them all together for an awesome galaxy effect!
What is really neat about this particular slime is that it changes its look the more that you play with it.
In the beginning you can really differentiate the three different colors of slime, but the more that it is played with the more the colors combine.
After playing with it for a while we added some star glitter to it as well, to give it even more of an outer-space effect.
Having a galaxy themed birthday party?!
This homemade galaxy slime would make a great party favor for the kids to give their friends. Simply place the slime in airtight containers and it will be ready to hand out.
Whatever your reason for making this galactic slime with the kids, they will certainly love it.

My daughter would love to make this!
How much slime does this recipe make? I’m planning a library program for 30 kids and would love to make it, but am worried it won’t be enough for everyone.
Hi Halli!
The recipe makes the amount of slime shown in the images, which I would say is a generous amount for 1 child, but would still be a decent amount to split between two or three children.
You could make one batch of slime together as a group, and have the kids take turns playing with it.
Or, you could divide the group into smaller groups of 2 or 3 kids each and have each group make a batch. Then split each batch into 2-3 “pieces” at the end so each child has their own slime that is still a good size to play with and enjoy.
This could get expensive fast, so I would probably recommend making one batch and having the kids take turn playing with it.
I hope you do get to make this awesome slime with the kids — it really is a lot of fun and I think they will enjoy it 🙂
This looks so cool! 🙂 I live in Germany and work with refugee children who are very into slime right now. I know they will love making this. I especially appreciate that it doesn’t require Borax, which isn’t allowed to be sold here. Anyway, thanks for sharing the recipe!
I love slime, but can’t find a recipe that will work! I will have to see about this one once I can get to the store!
