摘要 An educational amusement device imitates a canal, such as the Panama Canal. The device includes a base having a first water impermeable pan therein. An imitation terrain structure includes three dimensional forms extending upward from a top edge of the pan, and at least one further water impermeable pan therein. The first pan and the further pan are respectively connected to at least one connecting conduit lock to vary water depth between the first pan and the further pan, such as a fluid volume regulating one lock gate openable from a lowered closed position to a raised open position. The connecting conduit lock is in fluid flow communication between the first pan and the further pan. The base includes a bottom floor and a plurality of interconnected upwardly extending walls. One of the walls is a vertically extending transparent proximal wall providing a visual viewing image of respective interiors of the first pan, the further pan and the connecting conduit lock.
