Where we have air, we also have
air pressure. To each square centimeter of our body air applies 1
kilogram pressure. Just look at your hands; depending on the size
of your hands the pressure of the air on each of your hands may be
200 to 500 kilograms.
Our bodies are used and are
adjusted to such pressure. We will be in trouble if air pressure
stops in any way. With the enormous pressure of the air, I am
wondering if it can be used to do something like pushing, bending
or breaking objects.
I have heard that air pressure
can be used to crush metal cans and to push an egg into a bottle.
In this project you will investigate to see if air pressure can
really do any of these.
