The sandglass was made founded by the Schott Glaswerke (
visit link) to the city of Mainz.
The special glass cylinders turn around every hour controled by a microprocessor. The processor receives the dcf77 signal from the radio clock transmitter in Braunschweig (about 300 km north).
Nearby, you can found the Museum of Natural History of Mainz.
