The discovery of soap was one of the most important in human history. Just think about all the things we use soap for, from keeping clothes and dishes clean to sanitation in hospitals.
Today we make some kinds of soap using lye (which is leached from ashes), oils, and water, or we can buy ready made glycerin for our crafts. For this activity you'll use a ready made glycerin base to create elegant rose petal hand soaps—a far cry from the harsh lye soaps of yesteryear!
