Hubelino Ball Track - Extension 6 pcs, gravity hammer

If you're looking for ways to make the marbles move faster in your marble run, you'll love this Hubelino marble run expansion set. When a marble hits the gravity hammer, the hammer gives it fresh momentum and sends it further down the marble run at high speed. The pack contains 2 gravity hammers and 4 marbles. Suitable for children from 4 years old.

Smart fun with an emphasis on quality and compatibility

The parts are compatible with standard components from other manufacturers, so you can creatively combine them with your existing building sets and themed worlds. Like all Hubelino products, this set is made in Germany to the highest quality standards. The modular and compatible marble runs are designed to stay in place so children can focus on the fun. They promote spatial intelligence and an understanding of basic physics concepts like acceleration and gravity. Building a marble run stimulates working memory and improves analytical thinking, whether following instructions or during free play.
