For centuries, will-o\u2019-the-wisps\u2014eerie, blue flames floating over marshes\u2014spooked unassuming passersby. The strange aberrations inspired many supernatural interpretations, from fairies and ghosts to, of course, an adaptation as a\u00a0Pok\u00e9mon attack move<\/a>. But as with many seemingly supernatural phenomena, there\u2019s a very tangible, scientific explanation\u2014one scientists long suspected but have only now confirmed.<\/p>\n

In a Proceedings of the National Academy of Sciences<\/a> paper published on September 29, researchers explain that tiny lightning sparks jumping between marshy bubbles create will-o\u2019-the-wisps. Marshes and swamps are rich in flammable methane gas, and microscopic interactions between water droplets ignite the gas, according to the paper. In short, the ghostly flames are a product of chemical reactions occurring on a microscopic level.<\/p>\n

\u201cWe continue to discover things about water that, once you understand them, they\u2019re obvious, but before then, they seem completely bizarre,\u201d Richard Zare, study senior author and a chemist at Stanford University, told New Scientist.<\/a> \u201cNo one thinks of water related to fire. They think water puts out fire. They\u2019re not telling you with water, I can get a spark and set something on fire. This is new.\u201d<\/p>\n

Spontaneous \u2018microlightning\u2019 <\/p>\n

The new study builds on Zare\u2019s previous research<\/a>, which introduced<\/a> the idea of \u201cmicrolightning.\u201d This refers to a small flash of energy generated by electrically charged water droplets. Although water is typically neutral, exposure to the air can create positive or negative charges within the tiny droplets. The charge difference generates tiny electric fields that crackle into even tinier energy sparks\u2014microlightning.<\/p>\n

For the new paper, Zare and his colleagues focused on how microlightning could jump-start unintended chemical reactions. First, they designed a simplified version of the chemical conditions in a marsh, using a beaker of water with a nozzle to introduce methane and other gases. They captured the microscopic movement of the droplets by taking high-speed videos.<\/p>\n

As expected, when the bubbles slammed against each other, tiny light flashes emerged within the beaker. By applying some analytical chemistry, the team confirmed that microlightning was indeed triggering the reaction between methane and oxygen. The power of these sparks is enough to ignite methane gas, according to the paper.<\/p>\n

\u201cThis is really an interesting step forward,\u201d James Anderson, a chemist at Harvard University not involved in the work, told Science<\/a>. \u201cIt reveals a mechanism by which chemical reactions can be initiated.\u201d<\/p>\n

The origins of life? <\/p>\n

In their first work on microlightning, Zare\u2019s team hypothesized that the phenomenon could have \u201cprovided the sparks that gave rise to biomolecules necessary for life,\u201d Zare explained to Science. The new work \u201cstrongly suggests\u201d that microlightning indeed helped shape natural processes, in this case will-o\u2019-wisps, Wei Min, a chemist at Columbia University not involved in the work, told Scientific American<\/a>.<\/p>\n

Then again, it\u2019s important to remember that the experiment, while commendable, was strictly conducted inside a controlled laboratory. The dynamics of a real-life swamp are undoubtedly more complex. What\u2019s more, the absence of modern will-o\u2019-the-wisp sightings suggests as much, according to Antonio Pav\u00e3o, a chemist at Brazil\u2019s Federal University of Pernambuco in Recife who wasn\u2019t involved in the study, speaking to Science News<\/a>.<\/p>\n

Regardless, the results offer fascinating insights into a neglected natural chemical process. If anything, it\u2019s a phenomenon that warrants a closer look\u2014even if there aren\u2019t any ghosts involved.<\/p>\n","protected":false},"excerpt":{"rendered":"For centuries, will-o\u2019-the-wisps\u2014eerie, blue flames floating over marshes\u2014spooked unassuming passersby.
