Mr. Smarty Pants Knows
Plywood, water, the human heart, the kilogram, and Clint Eastwood
By Mr. Smarty Pants, Fri., Feb. 4, 2011
Only 1% of the world's water is in a form that is usable to humans. The rest is salt water or in solid form as ice caps and glaciers.
The human heart, full of blood, weighs three-quarters of a pound.
The standard for the kilogram – a chunk of metal, under triple lock and key since 1889 at the International Bureau of Weights and Measures in Sèvres, near Paris – is actually 50 micrograms lighter.
Clint Eastwood used to be a hay baler.
