Hoot Tubes

# 3D30.70

Description A Bunsen burner heats a screen in the bottom of a large open tube. When the hot air moves through the tube, it begins to resonate at the natural frequency of the tube. Different the length of the tube and the different material of the tube will give you different pitch of the sound.
Locaton Back corner of S101D
The clear plastic tube (42”Lx4.5”dia) will resonate at a certain point of a low flame while holding it above the flame. The iron tube (18”Lx 1”dia) will resonate after heating and moving away from the flame (the colder the better of the tube).
