The Endless hallway

This post contains no pictures. Sorry! Warning this post contains spoilers on how this feature of Disney's Haunted Mansion is done. You come up the staircase into a small sitting room. You see a suit of medieval armor aganst the wall. The voice that guided you this far starts to speak, and the armor begins to shake you look down a long hallway to see a hallway that stretches on for infinity! In it is a floating candelabra. The effect itself is simple. You can create one at your own home! All you need is two mirrors. If you position the mirrors so they face each other and look in one of them you will have an endless hallway.

This is the bacic trick . Now, the imagineers had to figure out how to let you see the hall because as we all know the back of mirrors are opeqe. If you sent the buggies through the hall you would have endless doom buggies as well, as it was they had to paint the back of the candelabra black so that you didn't see it. They decided that at the end of  the hall. was a regular  mirror, and they used two sheets of scrim to divide the hallway into thirds. This makes the hall seem endless. The candelabra hides the entrance and because the entrance is reflected very small because of the length of the hall. The scrim also makes things hazy so you can barley see anything. This is one of the most iconic illusions in the Manor.
