For this bath bomb, we crush the petals and stir them into the bath bomb. When the bath bomb is dissolved in water, fresh rose petals will float on the water. The white will dissolve in the water but it can ensure that the water is transparent, not like milk. That color also has bubbles, and we can also make water the color of milk. Blue makes the water like sea water, the kind of dark blue sea. When the two colors of white and blue are mixed, it is like a wave floating on the sea. You can enjoy the beautiful sea view in the bathtub at home.... http://www.bingzhicosmetic.com
