Making bath bombs

This week in science electives we made bath bombs  for Mother's Day which was a very fun activity.

When we were making the bath bombs we had to make sure we didn't put too much water and liquid on to the dry powder it was very challenging because you had to add water but you had to had the right amount or it would start visit in your bath bomb would be ruined. The results in the science behind our Observations 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.

Bath Bomb Recipe What you will need: (dry) - 1 cup of baking soda 1/2 cup of citric acid  1/2 cup of epsom salt (wet) - 1 tsp of water 1 tsp of essential oil 3 tsp of olive oil / coconut oil / Almond oil 2-3 drops of food coloring  Measure out and whisk together your dry ingredients in a large bowl. Next, in a small cup, mix together the wet ingredients. This is also where you’ll add the essential oils.  The next step is very important. Add the wet ingredients to the dry ingredients. You’ll want to do this very slowly, adding little drops at a time while mixing. The citric acid is what causes the bath bombs to fizz when it comes into contact with water. Adding the wet ingredients slowly minimizes this affect. Then, firmly press the mixture into the mould.  Let the bath bombs dry for at least 24 hours.
