Recently I have improved apparatus for the acoustic levitation of a drop of one liquid in another, making it practical to build for anyone who has an oscillaior and audio amplifier with response to 50 kHz, a current probe, an inexpensive oscilloscope, and a lead zirconate titanate cylinder of the right size. This piezoelectric cylinder (1.5‐in. o.d. and length, 0.125‐in. thickness) is epoxied near the center of a foot long piece of standard 30‐mm o.d. pyrex tube. A hollow piston with o‐ring seal and O. 005‐in. diaphragm acts as an excellent bottom, pressure‐release reflector of acoustic energy, as is the top air—liquid interface, leading to strong acoustic standing waves at particular resonance frequencies. Optimum frequencies are determined by observing the input current to the transducer as the oscillator is tuned between 47 and 55 kHz, and as liquid and piston levels are adjusted. Benzene droplets in water have been levitated with only a fraction of a watt input to the transducer. More details of this simple system will be described. [Work supported by U. S.
