Sound Levitation Breakthrough

This is a ladybug in mid-air. No, it is not floating because it is flying. It is actually being levitated and held in place by the force of sound (not by magnets or superconductors). Other small creatures like ants, tadpoles, and even fish have also been successfully levitated for half an hour using extremely high-frequency and high-intensity sound waves. Scientists say it would also be possible to levitate people-size objects, but the catch is that it would need wavelengths twice the size of the subject and a machine several floors high.
