Spring Doorstop Musical Instrument. Booooiinnggg!

posted by Jason Kottke   Mar 01, 2021

I didn’t realize it at the time, but making a spring doorstop keyboard was probably one of my greatest desires as a young child obsessed with those boingy door stoppers. We didn’t even have any of them in my house — playing with them was a rare treat when visiting friends’ and relatives’ houses. Thank you Ali Spagnola for fulfilling a childhood dream. (Can’t remember where I found this, but since it’s music-related it was probably via Ted Gioia.)

Update: See also the Quantum Garden, “an interactive art installation that demonstrates key concepts of quantum physics, such as quantum superposition, interference, and the Schrödinger equation.” (via @kayelcio)
