Abstract

High school students at the LBJ Science Academy constructed a hands-on acoustic levitation exhibit for Discovery Hall, an interactive science museum in Austin, Texas. In addition to the levitation apparatus itself, the exhibit includes posters that explain fundamental principles associated with acoustic levitation, e.g., vibration, resonance, standing waves, radiation pressure, etc. The project was sponsored by the Acoustical Society of America through an initiative of the Committee on Education in Acoustics to involve high school students in science projects based on acoustics. A review of the project will be presented in this paper. (The donation of a loudspeaker by JBL is also gratefully acknowledged.)
