Human: Is there a good way to make homemade soap without a fancy machine? Assistant: 
Yes, you can make homemade soap with just a few simple ingredients and some elbow grease. Start by melting 1/2 cup of coconut oil in a saucepan over low heat. Add 1 tablespoon of grated castor oil and 2 tablespoons of lye (lye is an alkali that helps the soap to harden). Stir until everything is well combined. Remove from heat and add 4 cups of water. Stir again until all the ingredients are completely mixed together. Place a lid on the pot and let it cool for about 20 minutes. Once cooled, pour the mixture into a mold or container and let it sit for 24 hours. After 24 hours, remove the soap from the mold and rinse off any residue. Finally, enjoy your homemade soap!
