The Arca Boxes

The Arcas are small aged switch boxes designed as an alternative to spirit slates for séance and other bizarre performances. A blank scrap of paper is placed inside the box, the lid is closed,  and the inset top is removed, revealing an arcane graphic. 

A ring, coin, or other small object is placed in the center of the graphic, which acts as a focal point, enabling a spirit to leave a short message inside the box.  At the end of the séance, the box is opened and the blank paper now has a message from beyond inscribed.

The Arcas are magnetic flap utility boxes, which can be adapted for most shows.  No routines are included, but the manual gives handling, tips, and ideas.
