Color-Changing Slime Kit: Galaxy
Free shipping in the US
Handpacked in California
Now contains biodegradable glitter!
Make your own color-changing slime! This recipe is easy to use and so much fun! This slime kit contains thermochromic pigment, which changes color based on temperature. So as you play with it, the slime changes from blue to purple! It's like magic! Try placing it in the fridge for a few minutes to cool it back down, or place an ice cube on top to watch it change.
This slime is not edible, but it is nontoxic and totally washable! It will stick to clothing and fabric, but is easily washable in a machine (and can scrub out of carpets as well).
In this slime kit, you'll receive the ingredients you need to make your very own stretchy, sticky slime, plus instructions that explain exactly how to make it. You'll get to mix the ingredients together using your hands, and watch it form as if by magic! It's a really interesting science experiment for kids!
This makes a great holiday gift for that science-lover you know, or that child who's always hands-on!
Other colors are available in other listings too.

I'm not sure if my daughter did something wrong and not really sure how she could when the color came in a packet. The room temp color of the slime is purple. The only way I've gotten it to turn blue was with boiling water. I have warm hands and have played with it for a good while but it doesn't change color at all. The slime is a little sticky but I think it needs more activator.
It was a great activity to do with my nephew. He loved that the slime changed colors. My only reason it is not 5 stars is because of how much wasted plastic there was at the end.
This stuff is the coolest, approved by four-year-old!!! And it really changes color.
