We proved that there is water in the air by doing a water condensation expirament. We filled a glass halfway with cold water and put a few ice cubes in it.
Then we left 1 glass on the table 1 glass in the refrigerator, and 1 glass in the freezer TOO! This is what they looked like after we took them out (10 minutes).
The water vapor in the air froze to the glass that was in the freezer, and the glass in the fridge got wet sort of like the one with ice in it. The one that was on the table did nothing. This proved that there is water in the air.
