Weighing the Air

Everything that is pulled down to the earth is done by the help of gravity.  It’s the force that gives things weight, whether it may be yourself, your pet, a car, and yes, even air.  That is what this experiment is all about.Materials Needed:  

A cane or stick about two feet

Two balloons


Step 1:  Tie a string around the middle of the stick so that the stick balances.

Step 2:  With some string, attach an empty balloon to one end of the stick and a balloon blown up with air to the other end.

Watch how the end with the balloon filled with air dips down.  With the help of gravity, the air in the balloon is heavier.
