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.”
- The KiwiCo Product Design team

I ordered this for my 2 kiddos - ages 6 and 3. They both needed my help to make it, but I expected that from start. It easily made 2 batches of slime and they are having a blast playing with it. The color change works great with an ice pack!
