It's going to fizz like it's insane!

Water is needed for the reaction to occur because is dissolves the solids and allows the ions in the acid and the base to move and collide with each other, causing a reaction to occur. This reaction forms carbon dioxide, which comes up to the surface of the water in the form of bubbles. And, of course, the oils and the fragrances are useful as a liquid to help form the bath bombs as well as cause the skin to be smooth and scented. The cornstarch acts as a liquid absorber to help keep the baking soda and citric acid from reacting with each other until liquids are added.
