Can sopranos shatter glass?
The One Show's Marty Jopson is on a quest to examine the truth behind popular myths.
The story that opera singers can shatter glass grew up around the great Italian tenor Enrico Caruso. It's said that he was able to shatter a crystal goblet by singing a note in just the right frequency.
Marty agrees that it could be possible. Every object has its own frequency and if matched, it is possible that the object will break. But can a human voice smash glass?
The answer: Yes, but amplification is required. Marty enlisted soprano Sarah Estill for his test. With the help of Salford University's acoustic lab, and a high speed camera, he managed to capture the moment that Sarah's voice shatters glass.
