A friend and I checked out a local "professional" haunt recently. (had a great time too, its still fun to be on the other side of the scares sometimes)
We are both firemen and something caught our eye. It was an unprotected fuse box off to the side a bit with exposed wiring, stabs, the whole bit. He points at it and is like "Wow that doesnt look very safe does it?"
About that time he steps on the pressure mat lol. It arcs and sparks and makes a helluvalotta noise! We both jumped and had a great laugh. Those guys did a fantastic job of making it look accidental, like its not supposed to be part of the show. It was absolutely my favorite prop of the whole place.
Anyone know how this is made? Or at least a site/pic where I can look at one to try and get a better idea of how its made? I've tried googling with no success. Also, any electrical guru types out there know at what voltages you can get a nice arc like that without danger?
