Invention Mansion is a modular playset that encourages freeform thinking. With four modular rooms that can be rebuilt in thousands of ways, kids never get tired of inventing. With the fundamentals of mechanical engineering dispersed throughout the mansion, kids cannot stop learning. There is a hinged trap door, a waffle zipline & flipper, and “get yourself dressed” linkage machine. Not to forget, it is an Oppenheim Platinum winner.
