Acoustic levitation is a spectacular phenomenon, perfect for standing waves demonstration. There are a few propositions for such a construction in scientific literature, however they are often expensive and difficult to build. The aim of this project was to create a functional stand - easy to construct, with no need for much expensive software or hardware. Piezoelectric transducers, typical for ultrasonic washing machines, were used as a sound source; their directivity pattern and frequency characteristics have been measured. The final result of the project was a stand-alone acoustic levitator with very little need for calibration, and with no walls, so the effect can be observed easily. The paper presents whole design process and describes all functionalities of the final stand.
