During a volcanic eruption in 1973 on Iceland the lava started flowing towards a harbor. Fishing was responsible for almost all of Iceland's income, so to save the harbor they decided to try and control the lava flow's path by pouring water on it. Day and night they pumped water from the sea on it and ran back and forth across the still not quite cooled lava, melting the soles under their shoes. The plan worked, and the harbor was saved.
In other words, Icelanders can walk on lava and control it's flow. I'm telling ya', that just ain't right!
