SHATTER A GLASS:) A human voice can shatter a glass. Every object has a resonant frequency - the natural frequency at which something vibrates. Wine glasses, because of their hollow shape, are particularly resonant. If you run a damp finger along the rim of a glass, you might hear a faint, ghostly hum - the resonant frequency of the glass. Or you can simply tap the glass and hear the same frequency. To shatter the glass, a singer's voice has to match that frequency, or pitch, and the glass must have microscopic defects.according to Jaime Vendera, a vocal coach who demonstrated his technique for the Discovery Channel in 2005. Conversational speech is normally around 50 decibels. A jackhammer operates at a loudness of about 90 decibels. The human threshold for pain comes at about 120 decibels. Highly trained opera singers can sustain notes above 100 decibels.

As an example of learning new things and thanks to the inspiration of a fellow Mingler, I got PADI (scuba) certified this weekend. It was an "I'd like to" when I was about 12 yrs old now resurrected. Very cool!
