Ravensburger GraviTrax Pro Extension Helix
More product information
Criss cross, under and over! With the Helix you can join up to six different tracks. When a marble enters the Helix it will move down to a lower level without changing its direction. Up to six marbles can pass through this Action-Stone at the same time! Combined with a Starter-Set, exciting tracks can be built without the marbles obstructing each other on their way to the finish. How many marbles can cross in your tracks? This set includes 1x Helix
This STEM system [Science, Technology, Engineering and Maths] is an ideal one to teach kids about gravity, magnetism, kinetic energy and fun. Hit a snag? Freestyle with your own track design or use the tasks and blueprints included to help you to get started in the world of GraviTrax! Are the gravity spheres stopping or flying off before reaching the end target? Time for some problem solving. Rebuild and try something different! The GraviTrax track system can be extended indefinitely with extra track packs and add-on’s – each sold separately. Suitable for ages 8 years and up. Fully complies with all necessary UK and EU testing standards.
