All kinds of things can be a reverb tanks. I've tried using a grand piano as a reverb tank with some mixed results. There's also a trick of making a weird reverb with a bunch of garden hoses of different lengths with a speaker at one end and mics taped to the ends.

If you dig fun reverb stuff, check out Stuart Dempster's recordings. His underground overlays album has trombonists in a large underground cistern with a natural 40 second decay.

I use a pedal based DSP stereo reverb to simulate spring and plate. (Ventris) My instrument make for playing with reverb. It is two strings with stereo pickup and played using a computer controlled rotary magnetic bow. (Electroduochord)

I found your YouTube demo of the Electroduochord from about a year ago. All very cool, thanks for sharing this!

I've released a couple albums solely using this instrument.

This one was done autonomously using a Puredata feedback loop. https://stefanpowell.bandcamp.com/album/autonomous-drone-lul...

All the code and the 3D model to build all of that is here: https://github.com/spDuchamp/OSCRMB
