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

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
