Can I order more?** A: visit, https://www.ravensburger.us/service/replacement-parts/index.html the mfg'r of the product. **Q: How many sets were used for the video?** A: starter Set and 3 extension **Q: Is there a way to make cannon less powerful? It shoots the balls out of the tracks and the layouts included do not work because of that.** A: Hi and thank you for your question. There is no way to make the cannon less β€œpowerful”. The best option is to work with the track pieces and adjust the set up so the cannon's energy is not as much when coming around the tracks. We also find that the cannon is great way to get your marble up a incline - gives it the extra boost of power that it needs! **Q: Can you buy extra colored Gravitrax marbles?** A: According to my grand daughter no, but it comes with plenty of marbles. ## Frequently Bought Together - Ravensburger Gravitrax Starter Set Marble Run | STEAM Accredited Toy | Ideal for Kids Age 8 & Up | Perfect for Endless Indoor Family Activity | Ranked No.1 Marble Run System in The U.S. - ThinkFun Gravity Maze Marble Run Brain Game and STEM Toy for Boys and Girls Age 8 and Up: Toy of the Year Award Winner - Snap Circuits Classic SC-300 Electronics Exploration Kit | Over 300 Projects | Full Color Manual Parts | STEM Educational Toy for Kids 8+ 2.3 x 13.6 x 19.3 inches --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.ke/products/71217415-ravensburger-gravitrax-starter-set-marble-run-stem-and-construction-toy](https://www.desertcart.co.ke/products/71217415-ravensburger-gravitrax-starter-set-marble-run-stem-and-construction-toy) --- *Product available on Desertcart Kenya* *Store origin: KE* *Last updated: 2026-09-14*
