This was not my first contact with the slinkyverb though. I'm pretty sure that was when I saw Moniek Darges and Godfried-Willem Raes and Moniek Darge I think she was hitting it with a stick and maybe also bowing it. It sounded pretty fine.
Today, I stumbled on this article about building a reverb with a slinky and it has kindled a desire to get some low-fi, low frequency reverb happening in my life.
I will also keep an eye out for telescopic antenna from an old radio or TV. I'm imagining the slinky in collapsed form for travel, then you simply set up and plug in, then extend the antenna to stretch the slinky out ready to perform.
