UVAcavs47 Posted November 21, 2005 Share Posted November 21, 2005 Hey, I was laying on my sofa watching tv and the glass in front of the fireplace randomly shattered (seriously, it just crumpled). Nothing hit it, and I am really interested in why it happened. Thanks, John EDIT: BTW, no fire at the time Link to comment Share on other sites More sharing options...

UVAcavs47 Posted November 21, 2005 Author Share Posted November 21, 2005 Nope. There are two sheets of glass so if I was wouldn't they both shatter? Link to comment Share on other sites More sharing options...
insane_alien Posted November 21, 2005 Share Posted November 21, 2005 could have been the thermal expansion combined with some vibrations at the right frequency. Link to comment Share on other sites More sharing options...
5614 Posted November 21, 2005 Share Posted November 21, 2005 I had something like this once... a pane of glass just randomly shatterred. Could be it had been under tension for a long time and slowly atom by atom the bonds were weakening. Or there was a sudden temperature change which caused expansion. Or sound waves.

Klaynos Posted November 21, 2005 Share Posted November 21, 2005 was the fire on? Link to comment Share on other sites More sharing options...

UVAcavs47 Posted November 21, 2005 Author Share Posted November 21, 2005 glass shattering God works in strange ways. ya know thats what i was thinking cause maybe that shattering would lead to us changing the fireplace and then a series of events etc etc Link to comment Share on other sites More sharing options...
Tetrahedrite Posted November 21, 2005 Share Posted November 21, 2005 sigh...... God didn't shatter the glass!!!! Link to comment Share on other sites More sharing options...
RyanJ Posted November 21, 2005 Share Posted November 21, 2005 A combination of some unltrasonic sounds and thermal differences (even small ones) could be responsibe when applied at the same time. Cheers, Ryan Jones Link to comment Share on other sites More sharing options...
Bluenoise Posted November 21, 2005 Share Posted November 21, 2005 A combination of some unltrasonic sounds and thermal differences (even small ones) could be responsibe when applied at the same time. Has this been proven to happen? There are alot of things that are possible but that are so rediculously improbably that they never happen and never will.

There are alot of things that are possible but that are so rediculously improbably that they never happen and never will. I think it has, minute changes and deviations in it glass temperature have a starting effect (same as larger temperature differenes just in small scale) which should then give the untrasonic sounds the ability to shatter it... maybe something worth testing out but has it been proves, I read it had but I'm not shure. I'll have to remind myself to book the school lab for tomorow so I can have a go. Cheers, Ryan Jones Link to comment Share on other sites More sharing options...
insane_alien Posted November 22, 2005 Share Posted November 22, 2005 if something was vibrating near the panes resonance frequency even a relatively quiet sound could build up enough energy to break the pane. done an experiment on this once. broke a wine glass from 20 m Link to comment Share on other sites More sharing options...
