Lava flow and two cans of Coca Cola. The first can had a tiny hole punched in the top to prevent it from randomly exploding. I wanted to see if it would fountain as it heated up but, the can just sort of squirted coke. The second can was sealed but, fell over. The lava caused a leak on the lower side. Footage is first from my Nikon D800 and then my old GoPro Hero 2. I had to pull the GoPro away at the end not from the spraying coke but, due to its proximity to the quick moving lobe of lava.
