Cloud Chamber
You're in your high school physics class talking about electrons, alpha and beta particles, ect, and you start to wonder.. How do we know that we are interacting with these particles, and how do we see them.
The answer for both questions takes us back in time to 1911, when Charles Wilson invented and perfected the Cloud Chamber, A device that was used to see the particles that surround us every day.
To make a Cloud Chamber its pretty simple actually. All you need is a sealed environment, radioactive source (which is optional), and dry ice or a cold plate with some kind of alcohol source.
Basically the particles make pathways through the condensed vapor. I have to say it honestly is one of the most astonishing things I have ever seen, and it truly changes how you view the entire world that we live in.
But to truly understand how amazing this is, and to learn about it if you're further interested, check out the wiki page!
