You can make different kinds of bath bombs, using different essential oils, different food colouring, flower petals or body glitter. They make great presents!
When you drop your bath bomb into water, this sets off a chemical reaction between the citric acid and the bicarbonate of soda. During the reaction, carbon dioxide is made, which causes the fizzing. The almond oil moisturises your skin and the essential oils smell nice.
