dude, yes sound waves can break glass... i thought everyone knew that

[aka5645]

u better believe it cuz its true!

[grownman455]

That is a nice party trick. haha

Sounds of other frequencies do bend the glass but the natural frequency of the glass is the frequency where the material's vibrational energy will grow to the highest magnitude sometimes enough to break the glass depending on the damping factor. If the damping factor is too high, energy is lost through air friction thus not allowing the energy to get large enough to break it.

very cool vid

@thekiyote That's a so to the point explanation! I understand the analogy completely! Thanks a lot ^^

@Earaem Picture pushing a friend on a swing. In order to push your friend higher, you want to push him while he's moving away from you. If you push him while he's coming at you, you're just going to stop him. The most efficient time to push is at the exact moment that he is comes to a stop before moving in the opposite direction. If you're off a bit, you can force your way through it, but in the case of sound and the resonant frequency of a wine glass, the force is very very small

Sound waves are shown to 'push' the glass at the point where the 'hit' it.

But why are soundwaves of other frequencies unable to produce the same effect (of hitting and pushing) ?

@EscapeDummy He was talking about glasses *bending* not breaking! Not everyone knows about the bending motion of the *rim*..

VERY nice video !

00:48 cartoon sound lol

@TheKingdomofErnor for sure. I used to not use the reply button, which is stupid and caused confusion haha.
