Boiling of water and a spoon is placed at the mouth of the beaker:
Steam loses heat and condenses to form water droplets when it comes into contact with the cool surface of the spoon.
Water droplets were seen on the outer surface of the glass containing cold water:
When the water vapour around the glass beaker comes into contact with the cold surface of the glass, it loses heat and condenses to form water droplets on the outer surface of the glass beaker.
