Sound Can Boil Water

While it might sound like science fiction, the energy carried by sound waves can generate temperatures hotter than the surface of the sun. This phenomenon, known as acoustic cavitation, occurs when intense, high-frequency sound creates pockets of low pressure in a liquid like water. These pockets allow microscopic bubbles to form and expand. As the sound wave immediately shifts to a high-pressure phase, these bubbles are violently and rapidly crushed, collapsing in on themselves in a fraction of a second.

This near-instantaneous collapse superheats the gas and water vapor trapped inside, concentrating an incredible amount of energy into a minuscule point. The process can generate temperatures exceeding 20,000 degrees Fahrenheit, creating a tiny, superheated
