Details

The smallest piece of ice was created by Roger Miller and Klaus Nauta of the University of North Carolina in 1999. Consisting of just six water molecules arranged in a hexagon, the ice crystal is the smallest theoretically possible, as a minimum of six molecules are required for the formation of ice. For comparison, the average drop of water contains around 100,000,000,000,000,000,000 molecules of water.
