Air Pressure
Introduction:  
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. 
 
 Project description:
In this project you will perform experiments to examine or demonstrate the abilities of air pressure to crush metal cans, push an egg into a bottle, and keep the water in an upside down cup. You can also perform experiments to see how the temperature causes expansion of air and use this property to construct a thermometer.
