Friction is a form of energy.

We did an experiment in school with our teacher. We needed a container, sharp pencil and some rice.

First, we filled the container with rice then we compress the air pockets, lastly we picked up the pencil with the container, it worked!

When two things rub together it makes friction. You will know when you have done it because you can hear the sound of friction and you can make a fire.

I think it is incredible that friction is able to do something like this and I wonder what we will find next.
