Tired of changing the batteries in your clock every month? Here is an innovative product that should interest you:the water clock . Yes yes to water!
As incredible as it may seem, the operation of this clock is based solely on water and not on batteries or electricity.
To operate the clock, there is no simpler since it is enough to fill the tank with water. And here it works! Couldn't be more practical, could it? It's not like you're going to run out of water at home, right?
In addition, this water clock is not outdone in terms of functionality since it also acts as an alarm clock, displays the temperature, and even acts as a stopwatch. Really a favorite of the editorial staff.
The water clock is a really smart innovation to save money easily. No need to plug your clock into the power or even buy rechargeable batteries to run it. A little water is enough!
I found a really cheap one at 11€90 on Amazon. Let me know what you think of it in the comments. Anyway, I've had mine for almost a year now and it still works great.
