Explore the Endless Possibilities of Physics with this Expandable, Compatible Marble Run Construction Set The 123-piece Basic Building Box was the first building box by Hubelino, a true classic. The set contains everything you need to build large marble runs: two base plates with 140 knobs, lots of run elements, building blocks and four colorful marble runs. With the instruction booklet and various designs of the marble run you will learn how the marble run system works and with your own designs you get a feeling for the numerous possible combinations. All building boxes are delivered in a solid cardboard case, so that the marble run is conveniently stored for home or travel. These modular and compatible marble runs are designed to stay put, so your kids can focus on the fun. They promote spatial intelligence and an understanding of fundamental physical concepts like acceleration and gravity. Whether with an instruction booklet or with free play, constructing a marble run stimulates working memory, and improves the capacity for analytical thought. And best of all, it builds on an existing system to extend its life. All 123 parts and components of the Basic Building Box are compatible with common components from other manufacturers and can therefore be creatively combined with your existing building blocks and theme worlds. Like all products from Hubelino, the Basic Building Box is manufactured in Germany under the highest quality standards.
