The other night at dinner my wife and I were making iced tea. We heated up a container of water, placed the tea bags in, and sat it on the table. While eating dinner, my 4 year old asks "Mommy, why is there smoke coming out of the tea?" My 7 year old responds "that's not smoke, it's tiny water droplets."
It took me a moment to realize that she was teaching my 4 year old science. She was absolutely right. We think of steam as a gas, but it's not. The iced tea is evaporating into the air, but as it evaporates into a gas, the gas cools and condenses back into tiny water droplets. The water droplets take on a cloud, or in this case, smoke type of an appearance.
This was a proud science Daddy moment!
