Amazing fact

Most popular myths in science - http://www.livescience.com


Chickens can live without a head

True, and not just for a few minutes. A chicken can stagger around without its noggin because the brain stem, often left partially intact after a beheading, controls most of its reflexes. One robust fellow lived a full eighteen months. Likely he was a real birdbrain, however.






A penny dropped from the top of a tall building could kill a pedestrian

A penny isn't the most aerodynamic of weapons. A combination of its shape and wind friction means that, tossed even from the 1,250-foot Empire State Building, it would travel fast enough merely to sting an unlucky pedestrian.





--
Water drains backwards in the Southern Hemisphere due to the Earth's rotation

Not only is the Earth's rotation too weak to affect the direction of water flowing in a drain, tests you can easily perform in a few washrooms will show that water whirlpools both ways depending on the sink's structure, not the hemisphere.
