All right, let's give you an introduction to explosives.
Something explodes because it is in a confined space.
A cork plugging the hole is not sufficient to keep the
gunpowder from simply burning quickly and popping
the cork.


As in when a cartridge in a gun is supposed to fire, and the "cork" (lead)
pop out through the barrel, but doesn't and causes the gun to "explode"?

As when a blackpowder M-80 is put into a mailbox, and the door doesn't "pop"
open to relieve the pressure, but the mailbox is destroyed?

Things explode all the time although they have a relief channel.

Where did you go to explosives school? I think you should ask for a refund.
What state do you live in? (other than the state of confusion) I want to
avoid that state in my travels.
