Can sopranos really shatter glass?
Tintin sure was surprised. His glass exploded as famous fictional opera singer Madame Castafiore hit a high note. But is it really possible?
Turns out, the answer is Yes. It’s a question of the frequency of the sound waves your voice generates. The principle is simple: every object has a natural resonant frequency, the speed at which it will vibrate if struck by the same frequency. When the human voice matches that frequency, it sets glass vibrating, sometimes enough to explode. It happens extremely rarely, but it’s not a question of power, just of hitting the right frequency. With a little practice, you too can shatter glass and impress friends.;)
