Cool water mapping tool [View all]

This has been around for a few years but is a great time killing and educational tool at the same time. Debated putting it in GD but it's not really political so I think it's Lounge material.

Click anywhere on the map and it will trace the route a water drop there would take to get to the ocean or other final destination. It even does a flyover of the route. I've spent hours on the site seeing what rivers and streams connect to each other.
