Perhaps one day humans will learn to control the weather. Future scientists simulate clouds and fog in a plastic bottle. They conduct an experiment where they place smoke and hot water in the bottle, then squeeze and release repeatedly. During the experiment, they consider how temperature and pressure affect condensation.
