These GIFs Of Objects Being Moved By Sound Look Like Magic

Forget superconductors and magnetic fields. Scientists from the University of Tokyo have developed a way to use sound waves to levitate objects and move them around midair. When a sound wave travels through air, it compresses air molecules as it rolls along its way. It creates a wave of pressure […]
