Are bath bombs really science? There was a post on Social Media of a Chemistry lab doing an inquiry lab with bath bombs. This is an excellent example of doing Chemistry labs on a budget. Make and put aside bath bombs as Christmas presents. Here and here are detailed lab instructions to make bath bombs. Test citric acid with cream of tartar. My bath bombs fizz too much when I make them. How does one keep the bath bombs from fizzing so much? Could you make bath salts instead? Are there different recipes? Which oils should be used? Does vanilla work as a fragrance? Could a drop of tempera substitute for food dye? Is tempera safe for skin? How much do the bath bombs cost to make? Would it be cheaper to buy them for gifts? Bath Bombs and Salts are also economic lessons. Organize your materials and make this an inquiry-based science project. (The image was posted in the National Chemistry Teachers Facebook group.)
