If you’ve ever wondered what the inside of a volcano is like then this cool video from National Geographic will give you a pretty good idea. Drones were used by explorer Sam Cossman to film the Marum Crater in Vanuatu and the results he achieved are spectacular. Not only did he and his team have to deal with the intense heat but they also faced serious toxic gases as they mapped out the volcano. Two of his drones didn’t make it out alive but thankfully all the humans did.
