ahhh..but you cannot shatter a crystal glass simply by running your finger around it. Unless of course you can make your fingertip do laps at an incredible speed. Your finger simply being on the glass affects the resonant tone of the glass and therefore it is nearly impossible to do it in that manner.
Also, contrary to common belief, for all practical purposes, even the best of operatic sopranos canNOT shatter a glass with merely their voice UNLESS it is a glass designed with this in mind. My high school choral teacher had done a project on this--turns out that demonstrations of that nature are 'rigged' in that the glass was designed with a resonating freq. in the a)audible human hearing range and b)one that could easily be sustained for a length by a skilled musician.
Bear in mind that those that are truly dedicted to having a 'thumping ride' are too into the quality of the sound they send soaring through the subdivision to possibly consider something of this nature. Being one in Pro Audio for a living right now, I can imagine it being a fun toy, but nothing to write home about or send out with U2 on their next American tour....its all about the quality! No sound-good, no thump-down-the-street!

Worse yet--furniture with maximum allowable db ratings...or UL listed tables?! eek...
