The World Meteorological Organisation (WMO) has announced its confirmation of the longest ever lightning strike, a gargantuan mega-bolt that stretched for more than 750km across three American states.
The flash actually occurred in April 2020, and was seen across a 768km stretch spanning Texas, Louisiana and Mississippi. This beat the previous record holder, a 2018 bolt in Brazil that stretched for 709km.
But how do you measure the length of a lightning bolt? One scientist, with a measuring tape, running really fast?
