This incredible video shows someone standing pretty much right inside a volcano, wearing a protective suit. But even with the suit, you've gotta wonder how they're staying so calm down there while lava is boiling up right in front of them.

It's a pretty stunning video, as most of the time we just see ash rising from a volcano and then the magma running down the side of the mountain. But to see the actual inside of a volcano like this in all its glory is really something else. Amazing stuff.
