Rainbow Slime Recipe

This Rainbow Slime is such a fun and easy activity for the kids! There’s a reason that kids love slime – it’s just so much fun to play with!

One of my favorite things about Spring is Rainbows. Yes, I know they do not only occur in the spring, but I sometimes think of it as such. The bright beautiful colors, mixed with the magic that occurs when sun and rain combine. This is truly one of the most charming spectacles the earth offers. I can’t help myself but stop in amazement when one surprises me!

My kids have a similar reaction when we made this Rainbow Slime Recipe. They were in complete awe! This is no surprise because this slime recipe is literally amazing! The process is simple, and the texture of this goo is one you just can’t stop squishing.

Not to mention the colors are right up there with the true-life rainbows created by nature. They are bright, bold, and just wonderful together. Whether you are making this slime for your kids at home or as a science center in your classroom, it is bound to be a hit with any kid!

In your remaining 1/4 cup of hot water, mix in your borax until dissolved.

Pour your borax water into your glue mixture and mix (slime will start forming right away).

Recommended Rainbow Activity Kits for Kids

These rainbow activity kits are a must-try and a perfect addition to your kid’s homeschool crafts or experiments. Kids will have a wonderful experience with these!

Make certain that you talk to the kids before you make the slime because they need to understand that it’s not going to stay rainbow once they start playing with it. They may want it to stay that way, but it’s going to get mixed.

And all this really means is that you’ll just need to make it again and can continue to make it over and over again easily every time.
