Rolex Time Sand is packed in 30 kg bags.

I guess it makes sense that if an hourglass were to have any chance of accurately providing some measure of time, the sand would have to be of a uniform size, consistency and texture. And if any company on Earth were qualified to produce a sand used for timekeeping, it would be Rolex. A single bag of Time Sand flowing through a standard hourglass is the equivalent of 30 days, and the pallets and pallets of sand you see below represent a generous estimation of an average human lifespan. (81 years)

(PICS)

The pallets of Rolex Time Sand were part of an art installation created by Michael Marcovici who’s also known for an installation where he stacked 10 million $100 US bills on 12 pallets to visually represent what $1,000,000,000 looks like.

On the 18 pallets pictured there are 972 bags with a total weight of 29.160 kg. They last for 81 years – our generous estimation of an average lifetime.

This image pictures the artist’s lifetime already consumed: 39 years
