This is a whole new level of bravery – the volcano diver

Marum Crater is one of earth’s most difficult volcanoes to access, but that didn’t stop Sam Cossman and George Kourounis with volcanic pioneers Geoff Mackely and Brad Ambrose. Against all odds they made their way to the edge of the crater and captured some of the most amazing footage of an active volcano we’ve ever seen. They made one critical mistake however, they forgot their marshmallows!
