Additional Info

  • ID Code: H3-16
  • Purpose: Show sound resonance created by convection currents in a tube.
  • Description: A gas flame is inserted into one end of the tube, heating the wire mesh which has been pre-positioned in the lower half of the tube using the plunger. Holding the tube vertical after the mesh has been heated red hot creates convection currents which enable the tube to resonate. Tilting the tube nearly horizontal limits the convection currents and the sound ceases.

    This can be an exciting demonstration, but requires careful handling for safety. Also consider H3-12 and H3-13.
