Behind the design


Getting the colors to change at exactly the right temperature was tricky. It took a lot of sampling and testing to figure out the balance, but now we know a ton about thermochromic materials in general.

By the numbers

Slimes made: 34

Ice cubes melted in slime: 50

Color changes seen during testing: too many to count!

So much fun! My kiddo loves making slime, it's a big go to in our house, but the color changing slime made it extra special. This is also a different recipe than what we use at home, which also made it a bit more exciting.

Worked as intended! Was so neat! Def wash your hands before and after using so that mold is less likely to grow on it.

I am very anti slime as a mom. Too much mess and rarely works out. But I figured if anybody could do it right KiwiiCo could. What a wonderful kit. My 10yo did this on her own - minimal mess and 2 lots of wonderful color changing slime. The only part that caused mess was cutting the tops off the dye. It splattered when I cut it but we’d got the table covered so no big deal. I LOVED that the kit included storage containers for the finished slime. A huge plus. The small work mat to cover the work area was good but not large enough. That being said I always cover the table completely before the children start a project like this so it wasn’t an issue. Useful work area to encourage keeping things together and not spreading them out everywhere! The color changing aspect is fantastic and provided a lot of fun. Well done KiwiCo. I still won’t attempt DIY slime on my own but this kit meant my daughter got to experience the science and fun of it and there was minimal cleanup for me!
