===== Purpose =====


To demonstrate that two glasses tuned to the same tone will vibrate together even though only one is played.  



===== Apparatus =====


Two or more glass goblets, water, toothpick or match stick  



===== Setup =====


  * Two glasses are filled with the same amount of water.
  
  * Place the glasses side by side so that at the closest point they are approximately 1cm apart (a little less is even better as long as they do not touch).
  
  * The match stick is balanced along the rim of one of the glasses.
  
  * Wet a fingertip and rub it around the edge of the other glass to create a tone.
