Gecko Run Marble Run Starter Set by Thames & Kosmos, Toy of The Year Win...

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. WARNING! Not suitable for children under three years. Small parts and small balls. Choking hazard.
