Thermocolor Slime
Make your own color-changing slime that changes from green to blue depending on the temperature. Ooze Labs are fun and simple science experiments in big chunky plastic test tubes! Each Ooze Lab tube contains a simple science experiment to create a safe material that is both fun to play with and chemically interesting.

Each tube has its own instruction manual to guide experimentation along with safe, non-toxic materials needed to conduct each experiment.
