@2009Fireblade Chuck Norris can break a glass by whispering at it
-
Justin beiber can do that too

that has got to be the most annoy sound ever....

but will it bend?

@iflamenko Does the resonance frequency of a glass is completely related with the glass material, or it has something to do with the dimensions itself?

@sirfreakman it does have something to do with the material, uniformity, etc. For instance, you could get a set of 6 or 8 wine glasses. Of course they have the same shape and even made out of the same material, but you'll find out that their resonance frequencies are different. You can even try buying expensive glasses that are very uniform which I actually did. Still, their resonance frequencies were somewhat different.

how many herts is that

@sammew123, from what I remember I think this one was over 700 Hz. Some other glasses I tried were around 450 Hz.

@iflamenko Just from being able to hear the glass in the background, you didn't match pitch at all. Having perfect pitch I'll tell you that glass was right around 620 Hz. Volume and imperfect oscillation allow one to shatter glass with the pressure, but this was not resonance match, sry.

@Icyveins906 We actually used this demonstration in the class to show that one has to match the resonance freq in order to oscillate the glass & then break it. 4 instance we tried neighboring freq & played with the strobe light, the glass wouldn't oscillate. We even used pith balls to bounce off of the glass as a visual indicator to show the resonance freq. Consistently, we had to reach the resonance or very close to it before oscillating and breaking it, otherwise it wouldn't break.
