It's just an old disconnect box that had two buss fuses still in it. I just rusted it up. Added some old extension cord wire(frayed the ends) some romex and stuck them in. I actually didn't have time to finish the flashing light (pneumatics and timing of the vid took too much time) so just added a small battery run strobe for the flashing effect.
I know in the video it's tough to see, but every time she grabs the door it pushed out. It actually became a problem, because when the video tripped, and she keeps yelling "let me out" people would grab onto the door handle and pull on it. It's attached to a pneumatic and I was afraid someone might pull the screws out. I should have put a chain on the door, so my guests wouldn't pull on the door....but we made it through the night with no problems.
