Using a technique that has possible applications in acoustic cloaking, sonic levitation, ultrasonic imaging, and particle manipulation, scientists at the University of California Berkeley claim to have produced a "bottle" beam of acoustic energy in open air that can precisely redirect sound waves. Able to bend these waves along set trajectories without the need for waveguides or other mechanical assistance, the bottle beam is also able to flow around objects in its path while maintaining its shape...
