Satellite To Test Relatively
dude_from_munich writes "Einstein proposed in 1916 that space and time form a structure that can be curved by the presence of a body. Scientists are finally planning to put Einstein's theory of relativity to test after a project delay of 44 years."

You are not alone. This is not normal. None of this is normal.

How to Build a Cloud Chamber
You can probably scavenge common felt and tape and a slide projector etc for free. You can buy pure (not 70%) isopropyl alcohol for about $7.60, and Dry Ice for probably $20 or less. I can pick up dry ice locally for $10. The issue with dry ice is that it will only last a day or so unless you get a huge block. I had a $40 block last 3 or 4 days.
Dry Ice is a real blast for parties, but at -109.3F / -78.5C you freeze-burn yourself pretty badly, and the pure Carbon Dioxide gas can be a minor hazard. Safety page here. With gloves, ordinary ventilation, and basic common sence you should be fine.
