Harvard Natural Sciences Lecture Demonstrations | The Wineglass That Won't Break @NatSciDemos | Uploaded November 2011 | Updated October 2024, 1 hour ago.
(Warning: obnoxious sound) For some reason I can't get this wineglass to break. It's an Oregon Balloon Wine 22oz. (made in Slovakia) from our local Crate & Barrel. It seems to respond really well to 454.72 Hz, with the lip moving at a pretty good amplitude...maybe it's hitting the speaker enclosure? Anyway, take off your headphones and enjoy watching the oscillations under the strobe light!
