For any holiday (as a favor) or just for yourself you can make these bath bombs and enjoy using them! The supplies are a measuring cup, bowl and wisk, baking soda, citric acid, witch hazel, fragrance oil, water free colorant, pipettes, a mini-muffin pan, wax paper. The batches here are 1 cup of baking soda to 1/2 cup of citric acid – which makes exactly 12 mini-muffin bath bombs. Start by adding one cup of baking soda to your mixing bowl and work out all the clumps. Next, add one half cup of citric acid to the baking soda – thoroughly mix and break up any clumps. To finish the craft look here and enjoy!
