To pilots, lift means the way that air holds up airplanes and other flying objects. These activities will show you how this force works--and they don't require a pilot's license.
USE YOUR LIPS TO LEVITATE
Hold a piece of paper between your thumb and forefinger, as shown in the picture. Now blow over the paper. What happens?
BALLOONS THAT BOGGLE
Try this activity with a friend. Blow up two balloons and tie each one to a string. Hold the balloons a few inches apart and try to blow them together.
Can you do it? What happens?
Try different ways of blowing on the balloons to see what happens.
(Hint: Squirt a little water into the balloons before you blow them up. This will help steady them.)
