EditTips

  • Use Crystal Glasses. They are much more likely to vibrate, and the sound quality is much better.
  • Patience is the key. If using a normal glass, it will take more time to get the hang of it. Though the wine glasses make better sound, it can be hard.

EditWarnings

  • Do not play it too long. Extended vibrations in the glass will cause it to break.
  • Do not squeeze the glass too hard. You may break the glass and/or cut yourself.

EditThings You'll Need

  • Glass (crystal wine glasses are recommended)
  • Water
