Scientists have found a molecule that can spin freely in liquid, clearing out water like a person swinging suitcases would clear a crowded room. The molecule spins without causing friction [Video]. That shouldn't be possible, according to a chemical physics theory. The finding could alter the way scientists think about chemical reactions in liquids.Researchers hit a drop of iodine cyanide and water with pulses from an ultraviolet laser, exciting one type of molecule to reconfigure into a small, peanut shape with a carbon atom on one end, a nitrogen atom on the other.The molecule heated up to 8,000 degrees Fahrenheit...
