Mythbusters is a great show in the discovery channel about 2 nerdy dudes who take urban myths (i.e. breaking glass with sound) and put them ot the test. they use lotsa scientific ways to prove if a myth is plausible or if it`s busted.
As oppose to American`s who are `oh my god, so normal?`
WWI was fought in Tacoma? A beidge made out of glass? No wonder it broke.
ah...you just barely beat me to it. Same idea of what caused the Tacoma Narrows bridge to fall.
It doesnt need to bve super high pitched, or very loud. You actualy only need to hit the resonant frequency of the glass to break it. All she had to do was get to the right frequency, and hold it straight for a while. If you waver, like most do, the resonance wont build, and the glass will not shatter.
It is a popular misconception that glass breaks at really high notes. Really what does it, is those that can hold a pitch.
I`m going to put that on my tomb stone.
It`s all in the physics. It can be done.
It should actually be "Woman" Shatters Glass etc.
Otherwise it would have to be "Women Shatter Glass with Amazing Voices."
However, in this case, there was only on individual shattering the glass, so it has to be spelled "Woman" as opposed to "Women"
The glass that she shattered for the commercial is now in the Smithsonian Institution`s National Museum of American History.
The phenomenon is called "Sympathetic Vibration"
I`m still skeptical as well, but stop analyzing everything. It was pretty cool.
It`s actually about your whistle register.
And yah, mythbusters cleared things up with their explanation.
