Go here to climb inside a tornado
It’s just about as close as you can get to safely getting inside of a tornado. Storm chasers got a multi-camera unit right in a tornado’s path. Cool!
I’ve driven (unwillingly, well, unwittingly, until it was overhead—you had to be there to understand why I was so stupid) under a funnel system that had touched down earlier and touched down again a mile or so later, and also driven as quickly as possible away from the path of one a few miles distant in rural Oklahoma one time, but seeing inside one—safely—is just cool.
