human may have thought they mastered the flaming back in the Stone Age , but hundreds of one thousand of years later and fire is   still a crusade of   fascination and confusion .

Scientists from the University of Maryland have draw a previously unobserved form of fervidness in a study published inProceedings of the National Academy of Sciences . Dubbed the “ blue whirl ” , the flame glows nearly altogether puritanical and speedily spins on top of a   body of water ’s Earth’s surface .

“ blasphemous whirls germinate from traditional white-livered fire whirls , ” Elaine Oran , Glenn L. Martin Institute professor of technology and co - author of the paper , explain ina program line .   “ The yellow colour is due to radiating soot particles , which mould when there is not enough oxygen to burn the fuel entirely . Blue in the whirl indicates there is enough atomic number 8 for complete burning , which means less or no soot , and is therefore a cleaner burn mark . ”

But this blue crack does n’t just make for a pretty picture . For one , it could be used to further the bailiwick of vortices and vortex breakdown in smooth mechanics . The researchers also believe it could have some real - life applications outside the laboratory , as   its properties provide a unchanging , clean , efficient , and leisurely - to - produce flame that   could be used to straighten out up crude oil wasteweir .

“ Fire whirl are more efficient than other flesh of combustion because they bring about drastically increased heating to the Earth’s surface of fuels , appropriate them to glow faster and more completely , ” explained Michael Gollner , assistant professor of attack protection technology and Centennial State - author of the paper , in the statement .   “ In our experiments over water , we ’ve see to it how the circulation flak spin generate also help to pull in fuel . If we can reach a United States Department of State akin to the blue pass at larger scale , we can further melt off airborne emissions for a much cleaner means of spill cleanup . ”

The researchers are not all sure of the mechanism that   forms the blue-blooded whirl . Regardless , they ’re still unrestrained about its presentation of high-pitched - efficiency , low - emission burning .
