The Rapid-Fire Launcher Expansion Pack includes over 20 components designed to enhance the Gecko Run Starter Set. It features a launcher that propels up to five marbles onto the track with a single button press. A built-in magazine collects marbles at the end of the run for quick reloading. The system uses flexible tracks made from renewable materials, enabling vertical marble run designs without additional support structures. The tracks attach to smooth surfaces using reusable nano-adhesive pads, which provide a strong but temporary hold without glue or residue. This allows for easy repositioning and mess-free setup. The open-ended design encourages experimentation with different configurations, promoting engineering concepts and problem-solving skills through hands-on play.
