Gavin Free and Dan Gruchy are the Slow No Guys, and they are in Iceland taking footage of Strokkur Geyser with a serious drone camera. In this excerpt from their YouTube show Planet Slow Mo, they use a thermal camera to give us a good look at the temperature difference between Iceland in winter and the geyser itself. We also get a cool explanation of how geysers work. -via Laughing Squid
