bath bombs are touchy for me, i love making them but the weather has to be just right or they just turn out gross and grow like the blob definitely try and tweek a few recipes, make small batches at first, try different oils and do alot of testing. i so hate botanicals in my bombs, lav buds look like dead flies floating in the water (yuck) and botanicals just stick to your wet skin. One little dried rosebud isnt bad, you can fish that out and toss it. If you really want botanicals or anything else that will "float" in the water, put your bomb in a organza or muslin bag and toss the whole thing into the tub. Ive never ever ever had luck with the plastic ornament molds, i use a piece of pvc pipe and a dowl that fits into it and i just pound the crap outta my bomb (tablets) its much easier for me to do multi colors that way. Its just about finding your recipe and playing with it. Ive made bath bombs with a bath melt bottom so you get a 2 in 1. Just play, be creative and have fun.
