Oranges may be an iconic fruit, but they are not a naturally occurring one, as The Telegraph points out. In fact, oranges are a hybrid of tangerines and pomelos, also known as "Chinese grapefruit," and they were originally green—not, well, orange.

In 1922, the American Association of State Highway Officials met to determine a standard design for stop signs, and that's where they decided on the color—yellow. Wait, what? Yes, according to Business Insider, stop signs were yellow because they thought that would grab drivers' attention. They'd also considered red, but there was no dye available at the time that wouldn't eventually fade. By 1954, however, sign makers had access to fade-resistant porcelain enamel, and could finally start making stop signs the red color we recognize today.

Researchers at Sandia National Laboratories produced the record-breaking temperature in their lab using a superheated gas, equal to about 3.6 billion degrees Fahrenheit

As the The New York Times reports, water on our planet may have originated from ice specks floating in a cosmic cloud 4.6 billion years ago. Not impressed? It follows that "the same liquid we drink and that fills the oceans may be millions of years older than the solar system itself." Something to keep in mind while you're staying hydrated!

The familiar bowler hat may look fashionable, but it began as a purely practical item—a riding helmet meant to protect riders from branches and other obstacles, according to The Telegraph. It was designed by London hatmakers Thomas and William Bowler, hence the name.
