In this clip from Australia’s The Curiosity Show, science educator and co-host Deane Hutton demonstrates the basics of sound, moving air particles, and forced vibrations with a plastic comb, hacksaw blades, the metal comb and bumpy metal drum of a music box, and a record-like metal disk.

In 500 episodes produced from 1972-1990, The Curiosity Show celebrated science, technology and things to make and do. Co-hosts Hutton and Rob Morrison won the rights to the show in 2012, and are sharing clips on their YouTube Channel for today’s generation of viewers.
