Density Facts

The density of Saturn is so low that if you were to put it in a giant glass of water it would float.

One cubic foot of gold weighs more than 1,200 pounds!

Milk is heavier than cream.

A neutron star (what remains after a Super Nova) is so dense that a portion of it the size of a sugar cube would weigh as much as all of humanity, or more than all the cars in the United States.

Kowloon Walled City crammed 33,000 people into just 6.4 acres - one city block. That made it the densest place in recorded human history. About 300 towers rose 14 storeys high, packed so close that sunlight never reached the alleys. Neither Britain nor China governed it, so residents built their own unlicensed economy. It was demolished in 1993-1994. The site is now a park.
