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.

I would love it if you included the measurements for the ingredients so that we could make them again using the equipment that was provided.

Had lots of messy fun with this crate! My son loved created the bath bombs and my youngest loved watching it fizzle up. It was fun for all of us. At first we all had a hard time getting the right consistency for the bath bomb but eventually got it. I always love how they provide everything you need!
