have attempted to explain the phenomenon scientifically. One explanation is that the fireball is a result of flammable phosphine gas generated by the marshy environment. Dunning writes that such fireballs are very unlikely to spontaneously ignite, and would not stay lit when at the speeds the fireballs travel, and that there is no science that can explain "the Naga Fireballs to be naturally produced burning gas bubbles." A similar explanation involves a phenomenon seen in plasma physics: free-floating plasma orbs created when surface electricity (e.g., from a capacitor) is discharged into a solution. However, these are produced under controlled conditions during plasma ball experiments using high voltage capacitors, microwave oscillators, or microwave ovens, rather than naturally occurring.
