Steve Spangler Science: Whirly - The Twirling Sound Hose

Whirling an ordinary, corrugated, plastic tube over your head becomes a musical experience.

A Sound Hose is a corrugated pipe (with ridges in it) that causes molecular gymnastics to occur when air molecules are moving through it. One air molecule causes its neighbors to vibrate at the same time it does and it becomes a musical party. Of course, there are only a few tones to hear at the party and you really have to work to hit the high ones… but, who cares? It’s all in the name of science!
