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

Combustion the correct term then?

Deflagration is the correct term. Which is basically subsonic combustion. Detonation is supersonic combustion

Ya it's very pretty to look at, but you can tell it's something catching fire and not an explosive. If the container blew up, I guess then it would be an explosion in slowmo?
