Craig sees a glass with ice tea sitting on the table. He notices that there is a great deal of moisture on the outside of the glass and a puddle of water on the table. He asks his family what they think causes the water to form on the outside of the glass. This is what they say...
Mom:The water is from the air being too hot The air is sweating
Dad: I think there is a hole in the glass
Sister: The glass was wet before you poured the tea.
Grandma: The water vapor in the air turns into a liquid when it touches the cold glass WHOS RIGHT??

Most likely grandma because its the most reasonable and if there was a hole in the glass then pretty much the glass would have broke. If the glass was wet before you poured the tea it wouldn't leave that much of a big puddle. Air doesn't sweat so mom is wrong.
