HE at Home - Chemistry


This box aims to give participants a hands-on activity which looks at the science used in everyday cosmetics. Learners will explore the science behind bath bombs by looking at the chemical equation and neutralisation reaction which takes place in the bath, all whilst creating their own bath bombs in the process.
