Review title is No Fizz [SEP] These were a disappointment. My 4 year old is very into bath bombs right now and we've been buying a variety of types and this has so far been the worse ones. They take FOREVER to fizz. Obviously my 4 year old has the patience of a...4 year old, so after 5 minutes of the slowest fizz on Earth, he took to slamming it on the tub to try and crack the toy out. They also don't smell great. If you're into super slow, non exciting bath bombs, get these. Otherwise, i'd keep looking. We will most likely go back to others we've tried.
