Today is Monday; I wake up at 6 o’clock in the morning. Then I have my breakfast at home and take the subway to school. I am quite excited about this day, because our chemistry teacher will teach us to do an interesting experiment. This experiment is about how to create soap. Last week, the chemistry teacher promised that we would have something fun in this week. Making our own special soap is the mission in this class.
When the experience begins, the whole class is very exciting; we mix the oil, water and lye. You need to be very careful, because the lye is harmful to the skin. Then we will stir the oil and lye for about ten minutes, the chemistry reaction will make the liquid into solid. Then the soap comes into being. Although the process is tired, we have a lot of fun. The most important thing is we learn how to make soap. The time passes so quickly, we feel very busy but learn a lot of useful things.
