As others have noted, the explosions seem fake. But I have seen that sort of UXO/Ordnance handling by, how shall we say, less than professional soldiers before. Most of near death experiences in the Army were from people handing stuff like this, poorly. Yikes. "You morons realize that thingy is supposed to explode, right? Maybe you want to handle it with care?"
This is right up there with smoking around ammo, especially M256 main gun ammo.
