  • Creative Design: This Marble Run Model Building Block Kit is equipped with a motor and a battery box (excluding batteries, requiring 6 No. 7 batteries), creating an incredibly creative marble counter model. Each block is meticulously designed, forming a unique and wonderful mechanical device. The tight mechanical linkage system and clever transmission structure will immerse you in the charm of block technology, allowing you to experience the endless novelty of this game cycle.
  • Ingenious Structure: The mechanical transmission design swings and pushes the balls into the ascending track. As the balls roll down the track, when the device is loaded with 10 balls, it swings and drops in balance, allowing 1 ball out of every 10 to enter the next track, while the remaining 9 balls fall into the transparent box. This design allows you to experience the charm of mechanics firsthand.
  • Play with Friends: This marble model building set is beneficial for learning basic engineering knowledge and improving children’s hand-eye coordination. It includes 2066 building blocks and can be seen as an educational toy for STEM learning, allowing children to integrate theory with practice, assemble and experience real physics principles. You can also build it with friends, establish relationships through teamwork, develop social skills, and solve problems together.
  • Assembly Tips: The ABS material is high-quality, non-toxic, odorless, and durable. It comes with a clear, colorful paper instruction manual to guide you step by step through the assembly process. You don’t need to worry about the assembly process; just follow the instructions to easily complete the assembly. We are willing to provide assistance if you encounter any problems.
  • Room Decoration or Gift: This marble computing model building kit has a black and gray appearance, with an elegant and classic design, making it an excellent decoration for your home, office, living room, or bedroom. Additionally, this toy building set is not only a dynamic display model but also a great gift for children, friends, or roller coaster enthusiasts. Whether it’s a holiday, birthday, Children’s Day, Christmas, or New Year, it’s a choice full of surprises and joy. As a highly ornamental building, it’s also worth showcasing and collecting.
