Doesn't decompose (in the explosion sense).. what DOES happen is that some
of it boils, is ionized, expands rapidly (mostly thermal expansion) driving
the rest out in particles... No special modifications at atomic level
needed, just ordinary thermal expansion

Nope.. it's magnetic forces doing the deformation (called, oddly enough,
magneforming, by the way)... The current induces a magnetic field, etc...
(Yes, of course there IS an electric field and hence an electrostatic force,
but it's orders of magnitude less)

streamer propagation in air is probably around 0.1 speed of light..
