How to make iridescent slime recipe with kids using our homemade crystal clear glue slime recipe.


There really is something to be said for playing with a handful of slime or goop. It’s for adults and kids and although it has become quite a craze lately, slime is a great science demonstration and a great sensory play recipe.

I just had a friend tell me she played with a load of slime I made for her daughter for a good hour because it was so fun!


Well, slime making is all about the recipe and although you can wing it a bit, it’s best to follow along. Like any great recipe, practice makes it better. Having the correct ingredients always helps. We have a whole post dedicated to slime supplies with a printable checklist.

I know for myself, sometimes a recipe goes really well and sometimes it doesn’t. If you have any trouble, contact me!

Our iridescent slime recipe is super easy to make with the addition of iridescent or holographic star confetti. Either the craft store or Amazon will have small, inexpensive packages of confetti.

Steps to make iridescent slime recipe for kids science activities

There are so many cool ways to make slime and play with slime. You can make them to showcase different themes for holidays, seasons, favorite characters and movies. We have a year of slimes to check out for cool ideas and we have a guide to making holiday themed slimes.

We also have a whole list of alternative slimes if you need a taste safe slime option or you don’t have certain supplies on hand. You can even make a slime alternative using just glue and cornstarch.

Make sure to store your slime properly, and it will last quite awhile. Longer then you might want it too in fact. I often will use plastic containers, but also like to use a glass container when I can. ALWAYS – wash your hands after playing with slime. Remember slime is a chemistry experiment!


What’s the science behind the slime? The borate ions in the slime activator {sodium borate, borax powder or boric acid} mixes with the PVA {polyvinyl-acetate} glue and forms this cool stretchy substance. This is called cross linking!

The glue is a polymer and is made up of long, repeating, and identical strands or molecules. These molecules with flow past one another keeping the glue in a liquid state.

The addition of water is important to this process. Think about when you leave a gob of glue out, and you find it hard and rubbery the next day.

When you add the borate ions to the mixture, it starts to connect these long strands together. They begin to tangle and mix until the substance is less like the liquid you started with and is thicker and rubberier like slime!


Once you learn the steps to make iridescent slime recipe, you can make any kind of slime! Remember, you might need to practice a few times to get it right. It’s important to not substitute ingredients or brands as the results might be different.

*Best time to add your confetti is after mixing glue and water together before adding slime activator. For complete steps, click on black box below. Find our printable slime recipes here.

*Many of our slime themes are interchangeable with the borax, saline, and liquid starch slime recipes. However, if you want a crystal clear slime, the borax slime recipe is the way to go. The others will be cloudy {but still a lot of fun}!
