bath bombs

in science we Were learning about bath bombs and the science behind 1 cup of baking soda 1/2 cup of citric acid 1/2 of epsom salt -1 tsp of water 1 tsp of olive oil/ coconut oil/ almond oil 2-3 drops of food coloring. I found it hard to mix the ingredients with the food coloring beaceuse I left it to long I found it easy to pour half of the ingredients in to the bowl I really enjoyed making bath bombs because I gave my mum the bath bomb on mothers day. Next time I will do other colors then blue and green because they are my favorite colors.

 When a bath bomb comes in contact with water, the baking soda and citric acid react to make carbon dioxide bubbles. This is an acid–base reaction, where baking soda (also called sodium bicarbonate) is a weak base and citric acid is a weak acid.
