Straw Oboe

Straw buzzes loudly like an instrument. Ask students to predict what will happen. Teacher blows into prepared straw reed. Key idea: The flattened reed vibrates and drives the air column. Ask: What part is actually vibrating? Safety and cleanup: Teacher-only mouthpiece; no sharing. https://www.google.com/search?q=%22Straw+Oboe%22+science+demonstration+experiment
