An explosion scatters debris during a live-fire demonstrationPeople living near Pantex are accustomed to explosions rocking the area.  Tuesday Pantex invited some of them to see what goes on at the plant.

Pantex tests and detonates a lot of explosives at the plant.  They don't hold many demonstrations but did yesterday.

There were three demonstration detonations.  Crews also gave a tour of a building never before seen by civilians or media.
