Here is a video that shows a good amount to put in the molds. I don't like his recipe for myself, but the technique is good. And it is pretty much the same as I do. http://video.about.com/candleandsoap/How-to-Make-Bath-Bombs.htm The first couple times I made mine, I packed it till my arms hurt and the ball would still push apart, I'm surprised I didn't crack my mold, lol. When I would get to the end of the batch and didn't have as much to pack, I realized they worked better. My last batch I got too wet. That was fun to see what happened then Of course it was with Patchouli EO, couldn't waste a whole batch on a cheap oil, had to be an expensive one. Good luck.
