WGR1 Wine Glass Resonator

The WGR1 contains a unique laser-sensing system to detect the motion of a wine glass and then feed back the signal to a loudspeaker. In this way the WGR1 places a glass at the heart of a positive feedback system in which the glass plays a crucial role in its excitation and ultimate shattering. During the glass motion, an automatic strobe system allows the motion of the glass to be viewed at a variable rate. The apparatus is supplied with full instructions for use including some detailed physics behind the demonstrations that can be done, as well as an accessory set including ear defenders and protective gloves for removing glass fragments.

"This is one of those demonstrations that you hear about being done, however its really got to be seen! The shattering of the glass is one thing, but to see the rim wobble back and forth by almost 1cm and have the glass not shatter is even more incredible..."

Product highlights

  • positive feedback based wine glass resonator
  • simple controls for finding the resonance frequency of a glass
  • automatic strobe circuit triggers as soon as the glass begins to resonate
  • gain control allows the vibration level to be gradually altered
