Coca-Cola

There are many stories of accidentally invented food: the potato chip was born when cook George Crum (yes, really his name!) tried to silence a persnickety customer who kept sending french fries back to the kitchen for being soggy; Popsicles were invented when Frank Epperson left a drink outside in the cold overnight; and ice cream cones were invented at the 1904 World's Fair in St. Louis.But no food-vention has had as much success as Coke.

Atlanta pharmacist John Pemberton was trying to make a cure for headaches. He mixed together a bunch of ingredients -- and don't ask, because we don't know; The recipe is still a closely guarded secret. It only took eight years of being sold in a drug store before the drink was popular enough to be sold in bottles.
