Secret Bells: Create your own personal sound system with a coat hanger and string

SecretBells DSC 3422 H

Another great activity from Exploratorium.edu! And most you probably already have everything you need to try this tutorial at home, which is always a plus.

Create your own personal sound system with a coat hanger and a string, producing musical sounds that only you can hear

Music and sound can really help you get young engineers engaged in a project. Some of our most popular learn guides for educators contain a bit of audio-focused fun as well – including this Sound Activated Shark Mask by Dano Wall.
