When it comes to rainbows, my kids are fully committed to them. If something has a rainbow, my kids want it or want to do it. Sometimes, I use rainbow colors just to get my kids interested in boring subjects. Rainbows are a welcome addition to STEM activities, which can get a bit colorless and bland if you’re not careful! Try out this rainbow glitter slime and bring your slime recipes to life!
This pretty rainbow slime is easy to make and also makes a fun addition to any rainbow science experiments.
You can also make these slime recipes at home for science learning and play on the weekends, or during any holiday break. Kids absolutely go nuts for the best slime recipes, and if you have slime lovers in your house, you don’t want them to miss out on making glitter rainbow slime!
How Do You Make Glitter Slime?
Clear Rainbow Slime Science
St. Patrick’s Day slime recipes are about more than just having fun with stretchy, gooey slime. Slime is a wonderful way to help children foster a love of science and chemistry.
Slime is formed when a chemical reaction between materials in the glue and the boron in the laundry starch or borax. This reaction alters the chemical bond of the materials, combining them into long polymer chains. This process is similar to how most flexible plastics are made today.
Making a variety of slimes is also a good STEM activity experimenting with how different ingredients react to make a variety of slime textures.
We make a St. Patrick’s Day version of slime because it’s a fun way to combine science and sensory experiences with St. Patrick’s Day!
Slime is also wonderful for kiddos who are sensory seeking, particularly for kids with SPD, autism, and ADHD.

While there are other ways to make slime, like with Borax powder and baking soda (we’ve never gotten contact lens slime to work), laundry starch slime is by far our favorite, and we will always recommend using it above any other recipe.

How to Make a Slime Rainbow
For this slime recipe, you’ll want to have a few things set up in advance. Most importantly, you need 6 containers for your rainbow colors. You can use mason jars or disposable cups. The advantage to the cups is that you can throw them away.
Inside each cup, you’ll put one part water and one part glue.
Dye each cup a different color of the rainbow: red, orange, yellow, green, blue, and purple (if you want to get really fancy you can use two colors of blue).
Stir the mixture and then add glitter. You don’t want to add the glitter first or it will all sink to the bottom and be difficult to stir.
Rainbow Slime Recipe Directions
Add one part laundry starch to each cup. Stir until slime forms. If you need help with the recipe, check out our basic laundry starch slime recipe.

The slime will be a little sticky at first, but that’s normal. After a few minutes, it will fully bond and turn into perfect, stretchy slime!
Arrange the slime into circles of red, orange, yellow, green, blue, and purple.
When mixed, the colors will run together, so what we like to do is pull off small sections of each color and arrange them into a rainbow and play with that until the colors mix, then we get new pieces to play with. It helps the rainbow last longer!
