Ball lightning can be reproduced experimentally

According to Pavo and Paiva, ball lightning persisted for as long as eight seconds and emitted jet plumes and smoke trails—both described in anecdotal accounts of ball lightning. Ball trails spiraled away, suggesting that lightning balls rotate. Color varied from blue to orange white; temperature was estimated to be around 2,000 degrees Kelvin (3,140 degrees F).
