STRING PIPES
National Standard: B2
“... Students should develop an understanding of position and motion of objects ... (both) can be changed by pushing or pulling ...” 1
Suggested Use
Loosen the string so it hangs freely. Now blow through the stem of the pipe, and the string will start spinning through the bowl. Rapid movement of air creates a drop in air pressure that drags the string along — the “Bernoulli principle” in action! Related concepts: hydraulics, pneumatics, flight, etc.
