It works.
"These were the first thing I used when trying to make 3 bath bombs. My bombs bombed. The first two came out in two haves. Tried to get them to go back in and stick which eventually they did, although one of them started to react to the water/alcohol I tried. The third one worked. I did not like the banging on them with a utensil because it left a mark. I wasn't really thrilled with them, but I'm going to try using a silicone spray and see if I can get them to come out easier. If I can I'll update this review."
