Crude attempt at ascii art to follow:

Slowly lower vertical tube over meeker burner

        |       |
        |       |     
        |       |
        |       |
        |       |     
        |       |
        |       |

You'll hear the tube start to "sing" at some point, adjust for maximum
volume by gently raising or lowering the tube:

        |       |
        |       |     
        |       |
        |       |
        |       |     
        |       |

It works sometimes with Bunsen burner or with propane torch, but Meeker
burner gives consistent results.
