Experiments:

• .Inflate the balloon using either four breaths or four pumps from a balloon pump.

• 2.Let go of the balloon while someone uses the timer to measure the length of time the balloon is in flight.

• 3.Why do you think the balloon flew through the air? As the air comes outof the balloon, it creates thrust that moves the balloon in the direction opposite of the air coming out.

• 4.Repeat the experiment multiple times with various levels of inflation (more or less breaths or pumps), recording the number of breaths and the flight time for each trial. Think of the air like gas in an airplane—the more you have, the farther it can fly.
