No way will an ammo box explode and send shrapnel flying. Even if filled with machine gun bullets and tossed in a fire. The rubber gasket fails and the pressure escapes. A slow burning object like a battery will never cause steel to fragment. If someone made a video it was faked
The purpose of the box is that first it offers mechanical protection in storage and transport and second it is a heat sink. If a few hundred watts of energy is put into a small part of the box, the heat conducts to a larger area and you have a lower temperature. The box is designed to store ammo in a combat area, the box will not explode if something inside of it catches fire. The gasket would fail first or it not the wire bail holding the lid would fail under minimal pressure. The lid opens LONG before the steel can bursts If I wanted to make a dramatic video, I'd fill the entire box with gun powder. The lid would fly open and burning powder would to ejected into the air and it would LOOK like an explosion On Sun, Jan 22, 2017 at 6:25 PM, Mark Sims <[email protected]> wrote: > They can be if you store them in something like an ammo box.
