I don't know if I'd like to try that one either - it sounds pretty gross!! But, ya know when I find things, I like to share it with everyone!!
PS I used to make my own hand soaps - using glycerin. I have a kit though that came with the molds to form the soaps...you can melt glycerin (maybe found at pharmacy, or a Hobby shop) and mix it with oatmeal or anything you'd like!
