It's an illusion similar to a pepper's ghost. Look at the floor, the one-way mirror there on the diagonal is the trick. You see the man on the other side because he's lit. The piston drives forward to right in front of his face, there's a flash, then you see the squished head. What's happend is during that flash, the light went off in the part the man was in, and came on in the reflected scene of gore, so that it is now reflected in the mirror.ok????? I see there is a piston that flies forward. Does the man step out of the way? I have never scene a transformation box?
I figure if I can figure out the spill your guts prop I should be able to figure this out.lol
But I need better pics, I never saw this in person.
