In 10 simple steps you will realize the experiment:

• In glass cup, we melt the drain opener in pure water and mix it with a wooden stick.
• Up to 150 degrees of temperature occurs. The mixture is left until it reaches room temperature.
• When the glass warmed up by the mixture becomes a little warm and the solution becomes clear, we add the mixture to the oil.
• Frying oil is added to the mixture when it has dropped to room temperature by mixing it with a wooden stick.
• Mix it for half an hour until it becomes a paste.
• Discuss with your peers how it turns into a soap.
• Discuss also how used oil pollutes the environment.
• The mixture is poured into a disposable container where it will take shape. The container, which is covered with stretch film, is also kept overnight under a towel and cover.
• The next day, after it was removed from the towel and cling film, it turned into soap like 6 weeks. I hope you will be satisfied using it.
• After 6 weeks, use it at home for 1 week. Then, bring it back to the class and discuss it with your friends.
