Aquarium Glass U Tube

Description

Got this tube a while back for a project that never really went anywhere — just ended up sitting in a drawer. It’s a 10mm glass U-tube, and I’ve got a photo with a ruler next to it so you can get a sense of the size. I’m not totally sure what it was originally for — probably something to do with air pumping or siphoning debris from the bottom of a tank, maybe with a plastic tube attached. Honestly, I just found it a bit useful and now I’m wondering if it might fit a different use. If you’ve got a project or just need something odd-looking and functional, I’d be happy to part with it. Photos are attached — no fancy words, just the real thing. Based in Canterbury, Kent.
