Not a clock with balls, but Time Machine

A very original replacement for the usual hand or electronic clock was found in the Amazon store: it is, so to speak, a ball clock that generates in its head inseparable associations with the Newton pendulum.

The principle of the device is very simple and clear from the photo: every minute one of the metal ball rolls onto the minute shelf, and, accordingly, every 5 minutes - for a five-minute one. The time period ends with a fall of one ball on a notch lined to 12, thus marking the beginning of a new hour.

Light metal clanging should be a fairly comfortable and rhythmic way to tell the time to the owner. Especially against the background of the price: only $ 25.
