For the music merit badge, my son needed to make an instrument and learn to play it. I remembered when I was a kid and watched Mr. Wizard made a double-reeded buzzer out of a drinking straw. Me and my brothers made a lot of those buzzers over the years. It’s a wonder that we made it out alive.
So, my son and I took that buzzer idea and expanded it into a really primitive oboe. We’ve been debating whether it sounds like a dying duck or a dying goose.
