A boy poured some boiling water into a plastic can and placed an air-tight cork on its open end. He then ran some cold water on it for about 20 seconds after which he shook the can vigorously. State and explain what he observed.

---

The can crushed inwards then it regained its shape.Shaking generate more steam in the can. The steam
generated causes arise in pressure in the can pushing the wall of the can outward and shape was restored.
