Videos and Pictures

I found some pretty neat videos that demonstrate the destructive nature of some disasters and also teaches us to respect the power of the destruction.

More videos are easy to find using Youtube. I found some pretty cool links that are both helpful and interesting. For example, search "How do tornadoes work?" and a multitude of links show up.
