Automated Fun: This set allows you to power up your marble runs by linking the beginning and end of the track via a radio frequency (RF) signal. Load the Starter with up to 7 marbles, and as each ball enters the Finish, it signals the Starter to launch a new one on its journey, creating a continuous and hands-free experience.

Compatibility: The GraviTrax POWER Elements Starter and Finish is completely compatible with all GraviTrax products, ensuring that you can seamlessly integrate this set into your existing track system. This means you can expand your marble runs with endless possibilities, adding new elements and accessories to create a variety of play options.

STEM-Friendly: GraviTrax construction sets, including this starter and finish set, are designed to promote STEM-friendly concepts.
