With a matchbox, pencil leads, battery, and wires, one can actually make a DIY microphone, and this video will show you how.
The steps are so simple, and you can use it to listen to sounds even when you are on the other side of the house. Aside from already mentioned materials, you’ll also need alligator clips and headphones to listen to the sound created by the matchbox microphone.
An overall fun and easy audio electronics project or a science experiment great to do with kids.
