In 1773 Ben Franklin noted in his diary that certain oils would spread out across the surface of water. Franklin observed that by pouring just one teaspoon of oil on water, it could spread out to form a thin film on the surface of a pond that covered an area of approximately half an acre.Though Franklin did not know this at the time, this film had a thickness of only a few nanometers.
