Today's science experiment was such an easy one. Guaranteed, you already have all of the supplies on hand. We made a cloud in a jar. It's a really fun way to learn about how water vapor can create the clouds we see in the sky.
Supplies:
A glass or a jar
A metal lid
Really hot water
Ice
Hairspray
We filled the jar about 1/3 of the way up with really hot water. My water comes out of my faucet scorching hot, but if yours doesn't, you can throw it in the microwave for a bit to warm it up.
Then, we placed the top on. (if you are using a jar lid, you don't need to screw it on, just put the flat piece on top of the jar) and cover that with the ice. I couldn't find my jar lid. So, we used the pan from the Easy Bake Oven.
Let that sit for about 30 seconds or so to create a little water vapor. Then, slide the lid halfway off and spray with hairspray and immediately cover it back up and watch the cloud form.
After you've watched your cloud form, you can remove the lid and watch it escape!
So of course it's not a "science" experiment without some science. So here goes!
Clouds are created when water vapor, an invisible gas, turns into liquid water droplets. Those water droplets form on dust or pollution in the air. Once, they settle on the dust or pollution, those white puffy clouds can be seen.
Maybe you heard people talk about how blue they skies were at the beginning of quarantine. Do you think maybe that was due to less pollution because people were staying in their homes and not driving places?
