A Sound Education: Glass Orchestra

Author(s): Gregory L. Vogt, EdD

Tap

Typical glassware is made of calcium carbonate (limestone), silica (sand) and potassium carbonate (potash). When a glass is filled with some water and tapped with a wooden mallet, it produces a thud-like sound. 

See the Notes section in the slide for materials needed, optional materials, setup instructions, and answers to questions.
