Gender Reveal Bath Bombs are for soon to be mothers. You can use these bombs at your gender Reveal party to surprise all of your loved ones, yourself or use it during bath time to let your kids know that they have a little brother or sister on the way. If you'd like this to be a surprise for yourself and/or your husband as well then all you need to do is tell your doctor to put the sex of your baby into an envelope and send it to me. This bomb takes about 15 to 20 minutes to completely dissolve.
