1. A nesting puzzle comprising: a compartment for holding at least one object or substance; a plurality of first, second, and third tiles for enclosing the compartment, each tile having inner and outer faces and a plurality of sides, each side including a junction, the first tiles including only inner junctions, the second tiles including only outer junctions, and the third tiles including inner and outer junctions; a plurality of rows individually rotatable in perpendicular directions to each other, each tile is included in two perpendicular rows; and a plurality of said junctions on a first plurality of said tiles collectively forming a key, the first plurality of said tiles forming said key having modified outer junction lengths and inner junctions distinct from the outer junction lengths and inner junctions of the remainder of the junctions in the puzzle, wherein when the junctions forming said key are all properly aligned by rotation into positions along two adjacent parallel rows, the junctions forming the key operate to attach or detach the tiles of the two adjacent parallel rows of the plurality of rows thereby splitting the puzzle into two sections to provide access to the compartment.
