The World's Biggest Sandglass

The world's biggest sandglass is located in Nima Sand Museam, Shimane Prefecture, Japan.

The sandglass was given the name 'Suna-goyomi', which means 'sand calendar.'

The height is 5.2 meters, the diameter of the container is 1 meter, and the diameter of the center nozzle is only 0.84 millimeters.

The total amount of sand is 1 ton, and it is falling at 0.032 g a second, 114 g a minute, 2740 g a day, 1 ton a year.

The fall speed is strictly controlled by pressure management using a computer.

The sandglass is turned over at 00:00 a.m, January 1st annually.

It was produced by Miwa professor, and the production cost was 100 million yen, the production period was three years.

I would like to see it directly someday.

By the way, the nozzle part is called 'orifice,' or 'hachinokoshi(means a waist of a bee)' in Japan.
