That was a great episode, creepy as hell. The ants ccoming in was a nice touch.
I wondered the same thing about the exploding box, all I could figure was it was in a pressure trigger so if the weight was too much or too little it would explode. So they timed it so they would pull him out at the same time they dumped the dirt so it would give them time before the weight of the dirt set it off.
That's what I'm going with anyways
