What is a Pepper's Ghost?

You’ve seen it in holographic displays in places like Disneyland’s Haunted Mansion, but home haunters are now using them for party and horror effects for the kiddies. These are so cool. It’s an interesting illusion that makes a ghostly image appear.

This article gives you a great explanation of the process.

The illusion is relatively simple by today's standards and involves principles we commonly experience but may not be aware of.

Clear glass, or plastic, allow you to see a reflected "ghost" image of something upon the clear surface, while viewing an entirely different scene behind the surface.

An example of this is when you have lights on inside your home and you look out a window at night. Often, you will see the interior of your house (and perhaps yourself) reflected in the glass.

Now, if you haven’t been to Disneyland’s Haunted Mansion—enjoy the ride. Someone videotaped it and put it on YouTube.
