YouTuber illustrates acoustic levitation in action

He makes pieces of styrofoam stand in mid-air
Loukia Papadopoulos

YouTuber The Action Lab has become a household name for conducting interesting and exhilarating science experiments that never fail to bewilder and amaze. You may remember this episode when he made a laser microscope using just a drop of water or this time when he made a black mirror.

In this exciting new episode, he uses acoustic levitation to make thin strips of styrofoam stand in mid-air just like magic. He does it through the use of an ultrasonic transducer and a reflector.

The transducer creates the sound wave required for things to float above it while the reflector regulates how far high they float. To make the experiment even more interesting, the YouTuber uses a second transducer as a reflector.

This creates even more powerful sound waves that can levitate even more objects. The YouTuber actually manages to levitate four pieces of styrofoam one on top of the other.

What other experiments does the YouTuber conduct with acoustic levitation? How heavy are the objects he manages to levitate? Why does he use a vacuum chamber in his other experiments? Watch the video to find out the answers to all these questions and more.
