Actually, the “Theory” bit is wholly extraneous. When your country’s biggest ammunition dump (at Balakleya, Kharkov) catches fire*, there’s no theory involved. It’s all about the big bangs.
This one is good, watch especially for the explosion at 2:06, the Ukrainian expression of surprise at 2:07, the ensuing shockwave at 2:16 and the slightly more animated Ukrainian expression of surprise at 2:18.
Basically we’re looking at big, uncontrolled, massively dangerous fireworks here. And how cool is that?
Equally cool is that someone took to the skies remotely with their drone and recorded it all from above, adding some wholly inappropriate background music.
Look out for that same HUGE explosion about halfway through this one, forming what looks like a terrifying smoky jellyfish.
