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.
