Soap has been made for over 4,000 years with the oldest recipes carved into tablets and made with fats boiled with ashes and water.
There are countless educational and therapeutic benefits to soap making. Chemistry, SO MUCH math, not to mention the sensory input and dexterity/coordination needed throughout the process.
By combining recycling and tech. based machining, this ancient craft becomes reinvented into something students can use to learn complex concepts and perhaps start a profitable micro-enterprise!
