Human: I'd like to know how to make my own soap. Assistant: 
Soap is made by combining lye with fats and oils. You can find instructions online or in books about making soap. You'll need some basic supplies, including a crockpot, lye (sodium hydroxide), water, oil, and fat. Start by melting the fats and oils together in your crock pot. Once melted, stir in the lye until it's completely dissolved. Then add the water slowly while stirring continuously. Finally, stir in any essential oils you want before pouring into molds. Let the soap cool and harden for 24 hours before removing from the mold.
