Accidental Pepper’s Ghost

This picture of a rare bakelite coffin in the London Science Museum’s plasticity exhibition is also an accidental recreation of the Victorian optical illusion known as Pepper’s Ghost.

In one version of the illusion, an audience member stands in the coffin on a stage, and the rest of the audience watch as he gradually decays into a dancing skeleton before their eyes.  In that case, the image of a brightly lit skeleton placed in a pit in front of the stage is reflected by an angled sheet of glass placed between the audience and coffin.

On similar lines, a less elaborate experiment you can try yourself with a sheet of plane glass and two tea-lights is described in this piece from the Naked Scientists.

I’ve had this picture for a while, and only noticed the Pepper’s Ghost effect when I pushed the shadow enhance slider on iPhoto.  Quite scary seeing oneself encoffined.  Good job I’m not superstitious….
