GraviTrax is a new STEM track system from Ravensburger which allows kids to experiment with gravity, magnetism and kinetic energy – learning as they play. My boys were really keen to try out this set, and we have been having a lot of fun with it.

The GraviTrax starter set comes with over 120 pieces included, and a booklet which gives you instructions and plans for a variety of easy, medium and hard tracks to build with the components included.

Among the pieces included you get 6 gravity spheres that will move along the track, rails of different lengths and to hexagon shaped pieces which can be built up to provide varying heights, bases to allow you to build multi level tracks and some cool feature pieces like a magnetic cannon and a free fall base, which let you add more variety to your designs.

Once you’ve made a couple of tracks by following the plans, you can also start to branch out to creating and experimenting your own tracks. I found free-styling with their own designs really got the boys thinking as they created the track by trial and error – considering whether the gravity spheres are moving too slowly, or too fast and flying off the track, then what do you need to change? With a couple of adjustments here and there, they soon managed to create some great tracks.

They had the idea to create a World Cup themed track, where they could launch two gravity spheres at the same time, with each one representing a football theme. Whichever one got to the end first, would be the winner of that match, so they decided to make this double sided track below.

And this is one of the simpler tracks we made, from the easy section of the blueprint booklet.

All of the tracks use the cardboard base to sit on, which makes them really stable and is a great idea. You can place the base on slightly uneven surface like a rug or carpet, and it still stays very stable which is great! The pieces don’t come apart by mistake when you’re building, which avoids a lot of frustration. We found the set very well designed, and easy to use.

GraviTrax is recommended for ages 8+ which I would say is about right, although slightly younger would be fine with it too. It interested all three of my boys, ages 6, 8 and 10. This toy can be played with just one player, or work together to create even bigger tracks.

GraviTrax can be expanded even further with extra packs and add ons – look out for our expansion pack review soon!
