In this video I show how to make a sound lens with a balloon filled with CO2 due to sound refraction. Then I talk about the possibility of creating sound lasers with ultrasonic hypersonic sound that uses modulated ultrasound through air. The air demodulates the ultrasonic signal to produce audible sound only in the area where the ultrasound is projected.
