The Build A Brick Roller Coaster
This is the 900+ piece interlocking brick set that forms a working 4′-long roller coaster. Paying homage to the classic wooden roller coasters of Coney Island, Kennywood, and Cedar Point, the model stands 12″ tall when assembled and sends its train plummeting through a series of drops and banked turns, all under the power of its own momentum. It snaps together easily by young engineers into trusses, towers, twists, and turns using the included instruction booklet.
