Not big. **Q: I wonder how high can a marble go, say on a 45 degree slope?** A: 45 degree slope seems steep to expect any upward movement. I would say not high at all. **Q: Is this for the tip tube or volcano? The picture is tip tube but the description is the volcano.** A: The manufacturer's answer is incorrect. Our order just arrived and it was the tip tube. ## Frequently Bought Together - Ravensburger Gravitrax Flip Accessory - Marble Run & STEM Toy for Boys & Girls Age 8 & Up - Accessory for 2019 Toy of The Year Finalist Gravitrax - Ravensburger Gravitrax Hammer Accessory - Innovative Marble Run & STEM Toy | Boosts Kinetic Learning | Perfect for Kids Age 8 & Up | 2019 Toy of The Year Finalist Supplement - Ravensburger GraviTrax: Jumper Accessory| STEM Toy for Kids Ages 8 and Up | Compatible with All GraviTrax Systems | Ranked No.1 Marble Run System in The U.S --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/148525240-ravensburger-gravitrax-flip-accessory-marble-run-and-stem-toy-boys](https://www.desertcart.us/products/148525240-ravensburger-gravitrax-flip-accessory-marble-run-and-stem-toy-boys) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-16*
