Water Clock
Runs on water. It needs to be topped off every couple of months, but other than that it is good to go. I would be curious about warranty information, but at $13.99…what is the harm?

This new tech came out in the late 1800’s. It actually runs on Zinc and a disimilar metal. I just did a quick google search for this. I’m sure there’s better out there.

I guess the ‘new’ part of this technology is that you can now buy it on the market. Thanks for the link on how the process works!
