Description

• 【Strong Motor】Containing 2438 bricks, this marble run set can be assembled into a spectacular model of a ball run coaster. The roller coaster toy set is equipped with a black furious hyperspeed L motor, which drives the transmission structure to push the ball, enhancing the novel game experience. The tight mechanical linkage system and the ingenious transmission structure will take you to feel the charm of building block technology. The finished model measures 23.43in(L)x7.87in(W)x29.69in(H).
• 【Ingenious Transmission Structure】The gear rotates to push the ball, and the electric lift steps transport the ball to a high place. The strong motor drives the rotating structure to push the ball upwards, and it goes through the bend smoothly. With the double wrap-around transfer line, the ball will roll happily on the slideway and finally roll into the storage box. Great Ball Contraption full of technology is rotated mechanically, and multiple modules are combined, which is very shocking.

You can feel the fun of hands-on building, get rid of the troubles in life, and relax. This roller coaster building set requires 6 AAA batteries (not included).
