The GraviTrax is an interactive track system where you can design and build your own marble runs and experiment with gravity, magnetism, and kinetics. With over 100 pieces and 18 different construction elements, including tiles and levels, you can essentially control the speed of the marble. The open-ended building concept offers endless possibilities for your kids and your family to design a different track every time you play. The toy comes with an integrated app to help you navigate through the system, manuals, and various tracks. The app also allows you to design action-packed tracks with the building editor and race using different balls and camera perspectives. You can also experience your track in action from the ball’s point of view using the virtual reality feature with a VR headset. According to Joshua, this well-thought-out toy allows you to be creative and emphasizes the importance of following directions. What do you think about the GraviTrax?
