Bath Bombs!

  

This term Room 25 have been learning about chemical reactions. We decided to share our learning with our families by making bath bombs to take home.

                           

The science behind it...

When baking soda and citric acid are mixed and are then put in water, they undergo a chemical reaction. The reaction produces lots of bubbles, which you see as the bath bomb dissolves in the water. These bubbles that make the water become so fizzy are made of carbon dioxide gas!

Here is the recipe we followed:
