chemproffag here… ammonium nitrate all by itself is NOT a high explosive. it's an oxidant. to make a high explosive with it you need to add fuel (eg, kerosene) that gets oxidized.
however, it's not rock stable, but decomposing pure NH4NO3 by itself would NOT produce the explosion seen in the video. something else cause the massive explosion, or the NH4NO3 reportedly "stored" there WAS being mixed with some sort of fuel (reductant) to make high explosives.
the white cloud that appears to "materialize" out of thin air is exactly that, water vapor (invisible) in the air that is condensed into liquid droplets (visible) by the hypersonic shock wave from the explosion.
