Color Changing Slime
- Grades 3-5
- Grades 6-8
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.”
