Does the marble roll fast or slow? The slide slows down the speed of the marble when rolling down, but the special shape makes the marble rotate much faster around ist own axis. The effect is well visible through the two-colored marbles. The slide is three bricks high and can be installed anywhere in the course of the marble run. It‘s best to place the slide where you can watch the two-colored marble spin around its own axis. Our 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. Wether 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, we’re building on an existing system to extend its life in the childrens room. All 12 parts and components of the Slide Accessory 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 Slide Accessory is manufactured in Germany under the highest quality standards.
