Resonance & Whirling Tubes

• Demonstrates resonance through whirling motion, helping students hear clear changes across 5 possible sound frequencies

• Also supports fluid dynamics teaching where airflow, motion, and sound behaviour are explored in practical lessons

• Approximate 73 cm pipe length provides a suitable format for visible and effective classroom demonstration use

• 32 mm pipe diameter supports the intended sound response during hands-on educational physics activities

• Lightweight PE construction at about 45 g per piece assists handling during repeated school and lab demonstrations
