Why does water become thinner and thinner after flowing out of the water pipe until it becomes drop by drop?
Hehe, high school physics knowledge can be explained. Because water moves at an approximately uniform acceleration. The flow rate at the outlet is constant, which leads to the water edge flowing faster and thinner (so that the flow rate can be guaranteed all the time, and the water column becomes longer in unit time, so it becomes thinner), which is drop by drop to a certain extent.
