Box of Darkness by Alan Wong
Box of Darkness is great for Halloween or any bizarre magic scene!
This is a mental dice box with a resin die that is made to look like a skull with amazing details.
A spectator rolls the skull die or selects any spot and places it into the box and closes the lid. Magician picks up the box and communicates with the skull inside to know what spot has been chosen. This can be repeated with phase two with the spectator not watching which spot and randomly place die inside the box and again magician picks up the box and communicates with the skull inside to know which spot has been chosen.
Standard mental dice box moves and routine but with a custom Halloween theme or any time you want to do some bizarre magic with good storytelling. It's for those who want something unusual and different!
