Cloud in a Jar

Today we created a cloud in a jar (twice)! It was quite a sight. We talked about the water cycle, how clouds form, and the "ingredients" to make a cloud. Here's a look at our experiment:

First, we made some predictions and wrote the steps to creating a cloud in a jar.

Next, we gathered the ingredients--hot water, ice in a bowl, an empty jar, and air freshener.

Then, we put the hot water into the jar and placed the ice-filled bowl on top. Within a few seconds, we could see condensation on the side of the jar. I quickly lifted the bowl and sprayed a bit of air freshener inside. This acted as the dust particles in the sky for the water vapor (as it's condensing) to stick to. This created our cloud.

After allowing the cloud to form for about 30 seconds, I lifted the bowl and the cloud floated up and out of the jar!! The students were so excited that we decided to give it a second try. Sure enough, it worked.
