Is there anything else that can be added to make bath fizzies perform better?
White Kaolin Clay is often added to make the fizzies harder and easier for transport. If you would like to use kaolin clay try adding 1-3%. Cream of Tartar is sometimes used to make the fizzing action last longer. If you would like to use cream of tartar, try adding 1/2 to 1/3 the amount of citric acid used in the recipe.
