>Wonder how many bars of soap
An average bar of soap typically weighs 3.5 to 3.75 ounces.
The average person has between 25% and 30% body fat
So a 100 lb person would contain about 25 lbs of fat. after processing with water, lye, and fragrance, the pre cured soap would weigh about (38 lbs times 16 ounces)/3.5 ounce bar = 174 bars of J-ass soap per 100 pounds of person.
