12 of48 Give Lift a Try! Training
  Book with paper and wind
Not convinced about this air speed business? Try this! Take a strip of notebook paper, cut in half lengthwise, and put one end in a book so the other end hangs over the top. This paper will be your "wing". Blow across the top of the paper. Because the air on top of the paper is faster, the pressure decreases and your "wing" will lift!
