Using the GraviTrax Zipline Expansion is easy. First, make sure you have the GraviTrax Starter - Set as it's required. Connect the zipline and the plastic tracks to your existing track sections according to your design. Place your marbles at the starting point and watch them zip across! When you're done playing, store the set in a dry place to prevent damage. Avoid bending the plastic tracks too much as they may break. Clean the tracks with a soft, dry cloth if they get dirty. Have a great time playing with your GraviTrax Zipline Expansion!
