Cool YouTube video series

Show CGI videos of what if scenarios, based on the most accurate physics and math and biology we know of.
E.g. if the world were split in half (sorry it is a gruesome example) how long until the rotation was thrown off, people floated into atmosphere, the lack of oxygen and pressure destroy them?
There could be hundreds of fascinating scenarios to enact, like the movies, but based on the most accurate, non dramatized science and depiction we can make.
If they became viral could make a few bucks.
