How do clouds get made again?

We love being scientists. Here we are seeing if we can make a cloud in a jar!

First we put some boiling water in a jar. Then we sprayed in some hairspray (this acted as the dust particles which float around in the atmosphere above us).

Next we put the lid on the jar. The lid was super cold because we had put ice on it. We needed to do this to simulate (that's a big word meaning " make it like") the colder air in the atmosphere.  The water evaporated  and as it rose up to the colder air it began to condense.  The water droplets attached themselves to the hairspray particles (just like they would in real life to the dust particles in the atmosphere) and formed our very own little cloud in a jar. It looked really cool and when we lifted the lid off the cloud, just drifted away!
