User: How do you make soap?
Assistant: Soap is made with a mixture of natural or organic oils, sodium hydroxide and distilled water.  When making soap you need to mix a combination of light and heavy oils like olive and coconut oil and then mix it with sodium hydroxide and distilled water.  After this mixture has been mixed well you poor it into soap molds and let it hard over the course of many weeks.  This process called saponification is the time it takes for the sodium hydroxide to evaporate from the mixture which causes the soap to harden in he soap molds.  Other options you have when making soap are to add essential oils, like lavender and grapefruit to give a nice scent to the soap.  This has to be added prior to saponification.
