You can learn how to make it rain by experimenting with a few simple items.

Making It Rain in a Jar

          Pour about two inches of very hot water into the glass jar.


          Cover the jar with the plate and wait a few minutes before you start the next step.


          Put the ice cubes on the plate.




What happens? The cold plate causes the moisture in the warm air, which is inside the jar to condense and form water droplets. This is the same thing that happens in the atmosphere. Warm, moist air rises and meets colder air high in the atmosphere. The water vapor condenses and forms precipitation that falls to the ground.
