Abstract
A time capsule includes a housing having a floor and an upper side wall extending upwardly from the floor and a lower side wall extending downwardly from the floor. The floor and the at least one upper side wall together define an upper chamber. The floor and the at least one lower side wall together define a lower chamber. A bottom wall is fixedly attached to lower edges of the at least one lower side wall so as to block access to the lower chamber. A lid is coupled to upper edges of the at least one upper side wall, the lid movable between an open configuration allowing access to the upper chamber and a closed configuration blocking access to the upper chamber, the lid having a lock that holds the lid at the closed configuration until unlocked with a key situated in the lower chamber.
