Color Changing Slime
- Grades 6-8
- Grades 9-12
Explore the science of thermochromism — with squishy slime that shifts color when it changes temperature! Mix and knead two batches of colorful slime, then draw on them with an ice-water-dipped stylus to see their color-change powers in action. Ready to have a slime of a time?
From the desk of the product designer:
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.”

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.

Really neat, a little messier than I thought.
