This levitator uses acoustic waves to hold things in mid-air — and this is how to make one at home. | Insider Tech

POW! ultrasonic levitation 🕹#powcademy ___________ Harvard's Wolfgang demonstrates ultrasonic levitation – floating small styrofoam balls in midair using only sound – and demonstrates exactly where in the air his 28 kHz ultrasound with a wavelength of 1.2cm creates pockets of high and low pressure, courtesy of a Schlieren Optics setup. ___________ by Harvard University Natural Sciences via Museum of Portable Sound & john cox | Powland

Acoustic levitation in construction may look basic now but this could be revolutionary once scaled up to say, the size of a pyramid...🔊🤯 | UNILAD Tech

Acoustic Levitation Explained Acoustic levitation is a technique that uses sound waves to suspend objects in the air without any physical support. By generating ultrasonic sound waves, which are beyond the range of human hearing, standing waves with alternating high and low-pressure regions are created. Objects can be trapped at the nodes of these standing waves, where the pressure is minimal, balancing the gravitational force with the acoustic radiation pressure. This allows for stable levitati
