"People asks" after reading

Today, I read "Pepsi." and saw a strange problem. Say: There is a place in Aegean Island called "Soap Island". When local residents wash clothes, they only need to grab a handful of soil on the ground to replace soap. Why is it so amazing? It turns out that the rock formations of this island are rich in alkaline substances. These alkaline substances are similar in composition to soap and can be dissolved in water. Of course, clothes can be cleaned. I didn't expect the soil of Aegean Island to be similar to the ingredients of soap. It taught me some scientific knowledge. Therefore, I have to study more, master more knowledge of daily life and science, and grow up to be a useful person.
