This marble run system features flexible tracks that enable vertical construction without support structures, allowing taller builds with fewer components. The tracks attach to smooth surfaces using reusable nano-adhesive pads, which provide a strong temporary hold without glue, residue, or surface damage. The open-ended design encourages experimentation with different configurations while developing engineering and problem-solving skills through hands-on physics exploration. The Starter Set includes 60+ pieces: 12 renewable-material tracks, 7 marbles, 40 nano-adhesive pads, levers, a funnel, and a bilingual manual (English/French). Recognized by TIME's Best Inventions 2024 and as a 2025 Toy of the Year Finalist.
