Ever wonder what the door looks like after a swat team sticks a breaching line charge on it?

basically, we built a special bomb, with three strings of detcord between layers of masking tape, then stuck it down the center of the door.

Detcord is a special explosive, a thick tube of plastic filled with a special mixture that doesnt actually blow up, but it burns so fast it sure seems like it.

It takes us about two seconds to stick this on a door, then another two to "breach".
