This almost looks like a magic trick, but it shows what can happen with very deep-seated fires, such as peat. Smouldering underground with limited oxygen, the very hot material and gasses can transition into flaming combustion once introduced to an atmosphere with a higher concentration of oxygen.
Mesmerizing.
