Evolution of the sodium-potassium alloy drop exposed to the action of the water vapor

Caption

The first image shows a pure drop of sodium-potassium alloy; in the next images, we see the drop exposed to the action of the water vapor at 10-4 mbar. A layer of water forms on the drop, in which electrons liberated from the metal dissolve, giving it a golden metallic sheen.
