Hi Folks
I'm not entirely sure that this is the correct sub-section for this post - but I think 'Close Up' is probably it.
I was just wondering where I can find the workings of the effect that David Blaine had in one of his TV specials (perhaps the Vertigo special) in which a wine-glass smashes?
I suspect a similar effect could be achieved through resonance - but it seems unlikely.
Incidentally, several years ago while we were enjoying our Christmas dinner, a wine-glass that was sitting on the table spontaneously smashed. No-one was remotely near it. I don't believe there were any 'psychic' phenomena involved (who would!) - and suspect either some form of fatigue or resonance effect. Perhaps there's a material scientist (or anyone) that might provide an explanation?
Cheers

Wine Glass Smash
Re: Wine Glass Smash
You could use an off-stage assistant with a rifle. :D
Or, as we did, we had a table with a spring loaded hammer that came up, hit glass and went back into the table at the other side.

Stay tooned.

Are there really people that can do this with their singing voice?
I've heard of people who sang sooo badly that animals went sterile :D

Re: Wine Glass Smash
A few years ago there was a clip on Tomorrow's World (a popular science show in the UK) where an Opera singer listened to the resonant note of a wine glass as it was 'pinged' and then sang the same note for a while and the glass smashed.
Many years later we did the same effect in the Science Festival, but we had to use a tone generator and a lagged box. I mentioned to the others the clip I had seen and the concensus was that they faked it :(
Theoretically all you would need is a loud note at the right pitch for a long time, so I still believe the woman did it for real.
Take care, Ian

Re: Wine Glass Smash
Is there some way you could pre-stress the glass, like Rupert's Pearls or tempered car window glass?

Re: Wine Glass Smash
If you brought any flaw into the glass it would affect the resonance, and the effect would be compromised.
