How… can voices shatter glass?
Cartoons of an opera singer shattering glass with their voice are common, but can this happen in real life? Every material naturally vibrates; this is because everything is made up of tiny particles called atoms, and these atoms are constantly moving. If a sound has the same vibration as an object then the object will vibrate more violently. These violent vibrations can cause glass to shatter. In 2005, a singer shattered glass by reaching 105 decibels (a unit measuring sound’s intensity) on a TV show called Myth Busters. The singer’s tone and volume vibrated molecules in glass at just the right amount for it to break. This is easier when singing into a microphone, because the tone and volume can be controlled.
