## Description

From the manufacturer Rocker extension (45 pieces) marble run extension With the plug-in marble run, where nothing shakes or slides, the little builders plunge into a colourful pleasure. Spatial imagination and first physical laws are playfully conveyed. All marble run products are 100% compatible with building blocks from other manufacturers and are made in Germany. marble run set With the 45-piece rocker extension, little builders can discover how the weight of the ball allows the two included rockers to swing up and down. The ball rolls up the rocker, in the middle, the rocker tilts over due to the weight of the ball and the ball continues along the track at additional speed. Made in Germany All Hubelino products are manufactured to the highest quality standards exclusively in Germany to ensure safe construction with high-quality materials and excellent product quality. Playful learning When constructing with the modular marble run, children's optical perception and logical thinking are playfully promoted. Thanks to the non-slip feel of the building blocks and track elements, hand-eye coordination and motor skills are also improved. 100% compatible All Hubelino products fit perfectly with the building blocks of other well-known manufacturers and thus expand the existing range sensibly for even more playing possibilities.

Review: Hours of fun - We have a large collection of these Hubelino sets. And by implication we also have a large box of official Duplo bricks lingering around even though the children have grown a little beyond their Duplo age. Every month or so we help them build intricate Hubelino marble tracks, sometimes up to the ceiling. So these Hubelino sets are brilliant. Already with a single set you can build a small run as basic tracks pieces and a couple of balls are included. But the fun really lies in the modularity and the ability to combine with other sets and your existing Duplo. This particular 45 piece set contains a base plate, a number of straight tracks, slopes, and various curves - the short curves are particularly helpful as are the basic white bricks that are included. The 2 main distinctive pieces are the rockers that allow the balls to create alternatives routes in you track layouts. Our only gripe is that the two rockers operate with some friction. So you will have to tilt them one way or the other and the ball direction is therefore not arbitrary The quality of the Hubelino tracks and parts seems very high, possibly even better than the original product, so the set is very durable.
Review: Rock away - Solid pieces that linked with duplo. The rocker is very sensitive and so the set needs to be on a hard flat surface to work well.

## Features

- Warning:Not suitable for children under 36 months
- Warning:Only for domestic use
- Warning:To be used under the direct supervision of an adult
- The 45-Piece See-Saw Expansion is already fun when designing, as its use must be carefully considered and it’s perfect for large marble runs. The marble rolls up the See-Saw until the weight of the marble shifts the center of gravity of the See-Saw and the marble rolls down the See-Saw with a lot of momentum
- 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. 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, we’re building on an existing system to extend its life in the children's room.
- All 45 parts and components of the See-Saw Expansion 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 See-Saw Expansion is manufactured in Germany under the highest quality standards.
