Hoot Tubes

PIRA: 3D30.71

Materials: Bunsen Burner, Propane Tank, Hoot Tubes (Various Sizes)

This demo is to show how different length cavities resonate at different frequencies. The longer the hoot tube the lower the note because it has less vibrations per second and amplifies a lower note. While, the shorter tubes amplify the higher notes because they have more vibrations per second.
