Yes, you can – this is documented since the 18th century. May 2005. At the time of the American vocal coach Jaime Vendera brought in the show “Mythbusters” on the Discovery Channel with his voice and a wine glass to Shatter. He was the First, the the front of the camera, succeeded, if only at the 20. Try. And he makes more On Youtube is at least documented, as he will be 85. Glass creates.
rumors that such a thing should be possible, there was earlier. The Tenor Enrico Caruso about glass blow were awarded at the end of the voting powers, where his wife, Dorothy, has always denied; in the home Caruso, the glasses are likely to be gone quite banal because of some blunders to break. The success of Ella Fitzgerald in a Memorex commercials from 1972 doesn’t count, too: her voice was amplified, and the volume is one of the key criteria zersingen the Glasses. In the cultivated mezzo-piano it will never work in a normal Fortissimo, too.
The second criterion is the frequency. Not high tones of it, do a glass, but rather those which correspond to the natural frequency of the glass are. As a crowd of people in step can put a bridge in vibration, can sound waves bring a Glaszum Vibrate – if you hit the exact pitch you hear when you strike the glass.
It needs a good blow
Mechanically, this is easy to realize, therefore, the Experiment is popular in the teaching of physics. Since a sine wave is set to the requested frequency and then turned up until the glass surrendered. The duration of the sound criterion number three is not a Problem; the machine sounds stop, until it is broken. A person must have been a pretty good blow, so that he or she holds out long enough. Even the loudest Kiekser on the right frequency brings no glass to break.
It is no coincidence that the Gläserzersinger sang Jaime Vendera in his youth in a rock band: Strong, direct voices have a better chance to defeat a glass, as a highly cultivated; even the layman, under certain circumstances, more than Opera singers. These have an advantage in terms of volume, because you can fill without strengthening a house. But you have a wider range of frequencies in their sounds; in addition to the glass frequency else resonates still. On the stage, their quality, the color of their Timbres. Scherbeln mind, for once in the literal sense: The others can do better.
