Two transparent boxes, each containing a marshmallow. A slow burn fuse cord burns visibly inside the first box, through a small exit hole, and to a small explosive charge on a lock securing the second boxes lid. The first box has a small, bladed mechanism which severs the fuse when the lid is open.
