Go Big Or Go Home: Round the World Edition We quit our jobs to go exploring before we are too old to hike up mountains and mountain bike down volcanoes. We may be a little crazy but we like it that way!

Blautopf (German for Blue Pot) is a spring in the city of Blaubeuren and a drain for the Blau cave system. The waters blue color is a result of physical properties of the nanoscale limestone densely distributed in the water. The particles are so small that the so called Rayleigh scattering of light takes place scattering the blue color in the visible light. Similar effect is observed in the Blue Lagoon in Reykjavik, Iceland.
