In this article, a simple experiment is described for correcting the misconception that acoustic pressure and levitation effects are hard to observe in school laboratories. Analysis of the free fall velocity of a toy parachute within a vertical tube, driven by sound in a range of frequencies around the resonant condition, exhibits the resonance frequency, the node pressure zones, and the optimal conditions to obtain acoustical levitation of a light body.
