For some time, the so-called Ames tube, consisting of a tuning fork combined with an open-end resonance tube, has been used in acoustics demonstration experiments. A few years ago, Malmark, Inc. designed a closed-end version with a handbell-type clapper. The Choirchime(trademark) has become a very popular musical instrument, especially in elementary schools and churches. Some acoustical features of Ames tubes and Choirchimes are demonstrated, and the ways they can be used in acoustics education are shown.
