Whirly: Twirl Sound Hose

Make music with a fluted sink pipe or irrigation tubing from the hardware store. Try out different sized pipes. What makes the best sound?

"Try attaching a plastic bag to the end of your Sound Hose with tape or a rubber band. With your mouth a few millimeters from the Sound Hose, blow into the open end.  The bag will inflate with just a few big breaths. Once the bag is inflated, twirl your Sound Hose.  As the "music" plays from the hose, watch the bag deflate"! via Steve Spangler
