Join us at Generations Park for a hands-on building challenge. Builders will receive a materials kit with the goal is to design a custom carriage that hooks to our gravity-powered zip line track, balances correctly, and moves smoothly.

This is a completely open build. Builders will rely on their own problem-solving skills to test friction and weight distribution, seeing firsthand how different materials change the speed of their carriage.
