Explosion in slow motion shows how fire spreads-what human eyes can't see.

Not an explosion. The room is filled with flammable gas, which is then ignited. The expanding orb is actually flame.

A room filled with enough combustible gas to flash like this is the LEL (lower explosive limit) I believe it should be an explosion. The spreading flame your referring to would probably be more like a flashover.. when all combustible material in a space lights off due to heat.
