Ben Franklin determined Avogadro's number within a factor of 5. He was able to do this by dropping 1 teaspoon of oil on a still pond and determined the area covered by the oil at about ¾ of an acre. You can simulate this by adding 1 drop of soap on the top of a greasy pan in the kitchen and watch the grease move to the sides. Sketch the interaction of the soap with the layer of water and sketch how the soap "dissolves" grease in water.
