I liked making them, but I thought the color would stay longer and that it would be more sudsy when I bathed with it.

My son loved making these and then using them at bath time. He had fun doing the store by step process and doing different color combos. He could not believe how fizzy they were when he got to used the finished product. He made a total of 5 bath bombs. This was such a good gift.
