Water Clocks April 29, 2008

water clockWhile we certainly don’t need to be wasting any more water, here is a cool invention that I’ve recently stumbled upon… a water clock. This clock runs strictly on water. No batteries or electricity needed. The water lasts months. Just add a little bit of water, and you will have a clock, thermostat, countdown, and alarm!

I am fascinated by this, so I mentioned it with great enthusiasm to my husband, the history teacher, and he told me, nonchalantly, that some of the earliest clocks were water clocks. What?! I never knew about this! Here’s a little background

It’s possible that the earliest water clock was made in China around 4000BC. They were mostly used for “astronomical and astrological reasons.” They functioned in coordination with sundials. Clocks weren’t essential until the Industrial Revolution, when people had to keep track of their time for wages.

Through the centuries, water clocks were used for timing lawyer’s speeches during a trial, labors of prostitutes, night watches of guards, sermons and Masses in church, to name only a few.

I guess you learn something new every day.

I think this would make a great gift. It looks cool and doesn’t require any energy! (the one pictured is just a clock. click here for the multi-function version)

    What a fantastic invention that I didn’t even know about either. Would make for a great Mother’s Day, Father’s Day or even Graduation gift. Of course I always ask for hanging plants for my old fashion porch. I may have to take a look at getting a few of those clocks.
