Lexus has released a new commercial showing its already sold out Lexus LFA supercar shattering a champagne glass using its exhaust note. The commercial shows the 552 Hp V10 supercar mounted on a dynamometer in a sound absorbing environment and accelerating until the engine revs to 7,000 - 9,000 rpm to generate the "magic note".
The Lexus LFA's exhaust generates the correct note that matches the resonance frequency of a thin, pure, crystal glass. This can push the limits of the vibrations of the glass until the stress becomes too great, and the crystal shatters. The shattering also depends highly on the shape of the glass as well as its thickness and pureness. (ehow)
If that explanation was too boring for you, the video is worth a million words.
