Get Water Out of Air by Creating Condensation
What you need:
What you do:
Put the ice cubes into the water then place a pitcher of ice water in a warm room. Observe what happens on the outside of the pitcher. Would covering the pitcher prove that the droplets on the outside did not come from within the container? Why do cold water pipes drip in the summer? Would the amount of moisture that accumulates depend upon the amount of humidity on a particular day? What happens when one blows hot air on a cold window pane? What do you think this condensation process has to do with rain?
