Human: How do I make my own homemade soap? Assistant: 
To make your own homemade soap, you will need the following supplies: lye (sodium hydroxide), water, fats or oils, a pot or bowl, and a spoon. Begin by mixing equal parts of lye with water in a pot or bowl. Make sure that the mixture is completely dissolved before adding any other ingredients. Next, add the fats or oils to the solution and stir until they are fully incorporated. Heat the mixture over medium-high heat, stirring continuously until it reaches about 150°F (66°C). Once at this temperature, remove from heat and pour into molds. Allow the soap to cool and harden for several hours before removing from the mold. Finally, cut into bars and enjoy your homemade soap!
