Bombardier Beetles Shoot Boiling Chemical Spray At Predators

When threatened, these beetles mix two separate chemicals, hydroquinone and hydrogen peroxide, in a special chamber. This triggers a violent exothermic reaction, producing a noxious, boiling-hot spray that can be accurately aimed and pulsed like a machine gun, deterring most attackers.

George Washington Never Actually Lived in Washington D.C.

Despite the city being named after him, George Washington never lived in the capital that bears his name. He oversaw the planning and construction of the city but died in December 1799 — before the federal government officially moved there in 1800. Washington spent most of his life at his plantation, Mount Vernon, located about 15 miles south of the city.

Beneath the U.S. Capitol complex runs a small, dedicated subway system known as the Capitol Subway System. It consists of two underground rail lines connecting the Capitol building to the House and Senate office buildings, allowing lawmakers and their staff to travel quickly between offices without going outside. The system has been in operation since 1909.

The Height of Buildings in Washington D.C. Is Strictly Limited by Law

A common myth claims that no building in D.C. can be taller than the Capitol dome, but the truth is stranger: the 1910 Height of Buildings Act limits most structures to no more than 130 feet (about 40 meters) on commercial streets. This law — not the Capitol's height — is why Washington D.C. has no skyscrapers, giving it one of the most distinctive, flat skylines of any major capital city.
