肥皂肥皂能驱动船吗?能!你可能不会相信,但这事儿千真万确!用剪刀剪下一块船形铝箔。在铝箔船上钻一个小孔。将一小块肥皂插进小孔,准备完毕!把船放进干净的水里,只见船开始徐徐前进。谜底在这儿!原来是水的张力在发挥作用。肥皂破坏了船后面的水面的张力。当肥皂溶解四散开来,其他地方的张力太小时,船就停下来了。 Soap soap can drive the boat? Yes! You may not believe it, but this is absolutely true! Cut a piece of boat-shaped foil with scissors. Drill a hole in the foil boat. Insert a small piece of soap into the hole, ready! Put the boat in clean water and saw the boat begin to move slowly. The answer is here! It turns out that water tension is at work. Soap destroys the water’s surface tension behind the boat. When the soap dissolves and disperses, and the rest of the tension is too low, the boat stops.
