I believe this is everyone's first exposure to the science of aerodynamics.
Intro to Aerodynamics 101
The science behind the play:
Aerodynamics = study of forces (wind, blowing into a straw) and the resulting motion of objects through
the air.
Play: the air you blow into the straw causes the paper to fly off. The harder you blow the further the paper will go. Blow lightly into the straw then blow hard. Compare the distance the paper flew. What happened?

Trajectory = the path of a object moving through space under the influence of some force (thrust, wind, gravity, etc.)
Play: blow into the straw while holding it level with your mouth and see how far the paper goes. Now tilt the straw up and blow. Compare the distances. What happened?
