A dancing flame demo?

A theramin demo?

Blowing cold air then hot air down an organ pipe - first
asking if the tome will rise or fall?

The always pleasing inhaled-helium speaking demo?

A whispering gallery?

A focused sound with balloon demo?

Demonstrate PC [free application] sonograms from student voiced phrases?

Voice spectrograms? [ditto]

It is just possible (I suppose) that students have never seen
tin can and string telephones?

Two loud tones with small deltaF to demonstrate beats
(Loud is always good, naturally! )
