NOTE: This slime explodes with rainbows using my very simple sprinkle tip! And while it looks good enough to eat, it most definitely cannot be eaten. Please make sure you only play science projects like this with kids of an age that can tell the difference in food and slime.

How to make Rainbow Explosion Slime with magic rainbows

Lets get started! First you need to create your fluffy slime! Leave it without coloring at all, so you just need your glue, starch, and shaving cream to get this going! Fluffy slime has a poofier more dense slime and the shaving cream additive makes it less sticky and more fool proof to original slime recipes. Of course if you are a novice, learn how to make slime without borax or check out all our slime recipes here. Tons of ways and no wrong way to play!

White school glue – I always use GALLON SIZED GLUE. Slime projects always lead to more slime and you cannot get a gallon in the store. I highly recommend just getting the big one as a more cost effective strategy.
Liquid Starch – This can be impossible to find, so also better to grab online
Nonpareils – You need tiny rainbow round sprinkles

Ready to make your slime explode with rainbows? Lets make that slime!

Start with about 2 cups of white glue – you don’t have to measure it, just eyeball it.

Now add some poofy shaving cream, I like the dollar store kind. My estimate is about 1 cup worth. Stir.

Starch time! Add about 1/3rd- 1/4th cup liquid starch to the bowl and stir. You will immediately see the slime form up. Continue stirring a minute or so and then pick up and begin kneading your slime. I have added a video below on how to make slime and can help you if you have questions. That slime does not include the shaving cream (in the video) but will show you the overall process of making slime if you need help.

Once your slime is made, sit down and let it flatten out. Sprinkle your nonpareils on and let sit about 30 seconds. This gives the coloring a chance to melt into the slime a bit. Now put your hand under and PULL!! See the rainbows!!
