Assorted Colours: You will receive one test tube selected at random
Simply empty the contents of the test tube into a bowl and add 220ml of water for instant slimy fun. When you add water to the polymers in the slime powder, it helps link the polymer molecules together. When enough of the molecules get hooked together, the solution changes into slime!
Features:
- A strange slimy science toy
- Comes stored in a resealable test tube
- Marvel at its appearance and behaviour!
Suitable for ages 6 & up
