haha! that's awesome! Never heard of brushing your teeth with soap before!!

Coconut oil soap is easy to make - actually any soap is easy to make by the cold process, if you're patient. You need a measured amount of fresh caustic soda - the amount depending on the quantity and type of oil you need to saponify. You make up a caustic soda solution of a certain strength (specified in books on the subject) and stir it into the oil. And wait. When the soap is completely set (takes a couple of hours), you drain off the liquid, which contains glycerin which you might have a use for. I've made a couple of batches of coconut oil soap here (Philippines), and one batch of olive oil soap (Marseilles soap) when I was in Europe. Nothing to it.

This is crank science. Somebody please put a stop to this.
