Timberdoodle's Review

With GraviTrax your child can design and build hi-tech marble runs while using gravity, magnetism, kinetic energy, momentum, velocity, and problem-solving to propel marbles to the finish. With this open-ended construction set your child will have access to two manuals. In the first, he will be asked to build a marble run precisely as pictured. In the second, he will be told the exact pieces and a few placements, but he will need to complete the design. Both booklets are color-coded, so your child can pick his preferred level of difficulty.

With over 100 pieces and 18 different construction elements, your child will learn how physics impact the track of his marble and how experimenting with height, curves, freefall, and even a magnetic cannon can be used to control the speed of the marble. Everything a STEM building set should be, GraviTrax combines physics, architecture, and engineering and will sharpen your child’s spatial reasoning, logical planning, and architectural design skills.

Gravitrax Scoop
Automatically triggered when the marble rolls into it, the Gravitrax Scoop picks up the marble, swings like a trebuchet, and lifts the marble to a higher-level track. The Gravitrax Scoop Accessory also includes six additional tracks and requires the parts from the GraviTrax® Starter Set.

Gravitrax Trampoline
How does bouncing change a marble’s speed? Find out with the Gravitrax Trampoline. The specially-angled height tiles and the two springy trampoline tiles allow the marbles to bounce to tracks waiting on the other side. Including two trampoline tiles and two angled height tiles, this accessory requires the parts from the GraviTrax® Starter Set.

GraviTrax Volcano
The GraviTrax Volcano unleashes explosive energy into your child’s track system! When a marble rolls into the trigger button of the Volcano piece, it produces an eruption launching up to 3 marbles down the tracks simultaneously. The GraviTrax Volcano comes with one volcano action tile and six tracks and requires the parts from the GraviTrax® Starter Set.

GraviTrax Flipper
Instantly flip your marble up a level in the opposite direction with the GraviTrax Flipper! How far will your child’s marbles go? Farther than you suspect! GraviTrax Flipper includes one flipper and six tracks and requires the parts from the GraviTrax® Starter Set.

    Gravitrax is fun for everybody!

    We bought this for my seven year old for Christmas. He LOVES it. He’s able to accomplish a lot on his own and has spent hours and hours designing new tracks. Several other family members also love it, from siblings to grandparents.

    Great substitute for physics lab!

    I got this set to use as a lab activity with my son's physics curriculum. Since there are two build options, we will use one as instructive/demo and one as sort of a lab test, if you will. I am sure my son will love this sort of test over a pencil/paper one. It will be so fun to have hands-on visuals to define concepts and vocab. I can't wait until we start! The only reason I gave it 4 star instead of 5 is because I do wish it had even numbers of all the components because we do like to do side-by-side comparisons to see how changing one thing will impact the result. I feel like that is essential to developing a scientific discoverer. However, one big bonus with this set that differentiates it from other marble run products is the open-ended directions in one of the builds. The students have to put what they learned and discussed from from the first build to use in order to complete the second project. It takes this set up from "toy" to science kit, in my mind.


    GraviTrax is very fun! I feel that every year, Timberdoodle find something even more fun for STEM than the last year!


    My son received the Gravitrax for his 10th birthday and immediately opened it and played with it for hours! He has really enjoyed the ability to make different courses, use a different amount of marbles and see the chain reactions he can create. Very fun addition to our hands on learning fun!
