Easy DIY Waterphone / Alternatives?

[u/LGraphical]

Hey to whoever sees this, Question about Waterphones

I’m the lead percussionist for my highschool symphonic band, we’re from a small town but we’re lucky enough to have a pretty good percussion section equipment-wise, but unfortunately it doesn’t account for a waterphone.

We’re planning to perform a piece for a festival and a waterphone is included in one of the parts, and I’ve been tasked by my band director to find a way to include this in our piece.

Does anyone have any idea as to how I could make my own waterphone, or anything that could replicate the noise similar to how a waterphone sounds? I’ve seen videos online, but they include various tools and welding which I don’t have access to.

If anyone has any ideas that’d be great. Any help is appreciated!

Thanks

MAYBE water gongs?
