We had no idea. The lines on a Solo cup correspond to typical ounce measurements of your favorite summer beverages.

This caught us by surprise. The venerable Solo cup, a wily veteran of countless BBQ's, graduation parties, receptions, camping trips, and many summer beverages has a trick up its sleeve: built in measurement marks.
The planet Venus is seen crossing the sun in June 2004 as photographed through a telescope at Planetarium Urania in Hove, Belgium. The earliest known observation of such a transit was in 1639 by English astronomer Jeremiah Horrocks.

In an age when the size of the observable universe is known to a few decimal places, today's Transit of Venus offers a good opportunity to reflect on just how far we've come.
Less than 250 years ago, the brightest minds of the Enlightenment were stumped over how far the Earth is from the sun. The transits of the 1760s helped answer that question, providing a virtual yardstick for the universe.
A rare astronomical event will take place Tuesday evening: The planet Venus will pass between Earth and the sun, appearing as a small black dot moving across the sun's bright disk. It's known as the transit of Venus, and it won't happen again for more than 100 years.
The early word is that it could have been worse. The steel and aluminum dome atop the Mount Evans observatory was destroyed by high winds over the winter. But damage to the telescope inside may not be as bad as first thought.
Safety over style: In 2006, a Palestinian man and boy were careful to protect their eyes while watching a partial eclipse of the sun. The same cautions are in order for Venus' transit of the sun on Tuesday.
