Connect the height tiles and tracks to form your desired path. Ensure all connections are secure to prevent marbles from derailing. Experiment with different elements like the Trampoline, Zipline, and Magnetic Cannon to add complexity and excitement to your track.

5. Operating Your GraviTrax Set
Once your track is constructed, place a marble at the starting point (e.g., the Launch Pad). Release the marble and observe its journey through the course. The GraviTrax system demonstrates principles of:
- Gravity: The primary force propelling the marbles downwards.
- Magnetism: Used in elements like the Magnetic Cannon to give marbles an extra boost.
- Kinetics: The study of motion and energy transfer as marbles interact with track elements.
Experiment with different marble release points, track configurations, and obstacle placements to understand how these factors influence the marble's speed and trajectory. The goal is to guide the marbles from start to finish using the various elements provided.
