If you have a toy that is "plastic" and "squeezable," what happens when you let go after squeezing it?
It turns into a liquid.
It likely returns to its own shape because it is a solid.

Imagine you are building a new playground swing. Why would you choose "strong" and "hard" materials like wood or metal for the frame?
