Friction

Friction is a type of compressed energy but it is also a force.

You will need a small container any type of rice. In addition to that you will also need a pencil with a sharp edge.

Firstly, get your container and fill it with rice, then get the sharp end of the pencil and push it up and down repeatedly. Although it gets difficult to continue pushing, you have to keep going until all the air bubbles are compressed out then, the rice will grip the pencil.

Friction occurs when two things rub together.

In conclusion, I think it is very interesting how friction can lift the container and the container  didn’t fall in spite of its weight.
