Tips
  • To produce resonant frequencies of the tube and to demonstrate standing wave resonance in an open tube hold this Twirl-A-Tune by one end, keeping that end free for the flow of air, and swing it around your head. Increasing the speed of the rotation raises the harmonics produced.
  • Up to seven harmonics can be produced, illustrating the notes of the overtone series. The fundamental can only be produced by blowing gently into one end.
