Cooling the Air in the Cave

A magma chamber beneath the cave heats it all to something around a hundred and 36 degrees. To film in the cave, george and his crew had to wear these refrigerated suits with fighter pilot like masks that cooled the air that they breathed. The coolest thing is you yo include the inside of your lungs so that that very dense, humid air wants to condense into water droplets. You can drown in the cave without there being any water around you.
