That's a volcano flow, in case you hadn't noticed, and that's a guy in a suit he and a couple of friends rigged up to help withstand the deadly temperatures of molten-hot rock. Geoff Mackley, Bradley Ambrose, Nathan Berg built the respirator and heat proximity suit themselves, but details are scarce (read: nonexistent) about how they put the thing together, or which one of them is standing at the brim of a lava lake in this video. Without it, a person can stand beside the lavafall of Manum in Vanuatu for about 6 seconds. With it, the team reportedly hung around for 40 minutes. Link -via Motherboard
