## Description

Ravensburger - GraviTrax - Colour Swap Element - 26815 - STEM Building Set - Extension for Creative Ball Circuits - Ages 8 and Up - French Version

## Features

- COLOUR SWAP: A clever tunnel-shaped action block that gives the illusion of changing the color of a ball. With a clever sleight of hand, the ball reaches inside the block and comes out in a different color. A magic trick that is easy to master, but sure to give a spectacular effect in a GraviTrax ball circuit!
- Infinitely adaptable and compatible with all GraviTrax products. This element is played with at least one Starter Set (essential to start) and then combines with all GraviTrax ranges. Discover a wide choice of expansion sets and elements to enrich your circuits and imagine an unlimited number of different courses.
- CONTENTS: 1 Colour Swap Action Pad, 3 Balls, 1 Illustrated User Guide
- An ideal gift for girls and boys aged 8 and up, and for construction fans of all ages! Made in Europe with high quality materials, GraviTrax is built to last and guarantees hours of play and assembly, alone or with others. A perfect gift idea for a birthday or Christmas.
- STEM EDUCATIONAL GAME: GraviTrax is a very playful building system that allows children to experience physical laws such as gravity, magnetism or kinetic force. By manipulating the blocks and testing their own assemblies, they develop both their creativity and their understanding of these scientific principles.
