Ravensburger GraviTrax Spiral Expansion Set

Your marble run creations will experience high-speed vertical exhilaration with the Ravensburger GraviTrax Spiral Expansion building kit. This addition, which is made to operate with the GraviTrax Starter Set and other compatible systems, uses dynamic spiral elements to enable marbles to descend quickly from one level to another. When creating intricate tracks, the set's two varying-height spirals provide builders greater freedom and artistic control. This STEM-focused add-on promotes experiential learning about motion, gravity, and engineering principles and is perfect for kids ages 8 and above. Create exciting, fast-paced, action-packed marble runs as you expand your GraviTrax universe. 

Delivery Costs, Ireland and Northern Ireland

• Free delivery on orders over €70. Under that, delivery is €7.
• Large items — go-karts, swing sets, playhouses and the like — are delivered free of charge, anywhere in Ireland and Northern Ireland.
• International delivery is calculated at checkout.

Delivery times

Order before 1pm, Monday to Friday, and your order is usually on its way the same day. Most orders arrive the next working day, and nearly all within two. Very occasionally — during busy periods like Christmas, or if our courier runs into a delay — it can take a little longer, so please allow up to 5 working days.

Bulky items

We deliver large items ourselves rather than hand them to a courier, so they arrive properly and in one piece. That takes a little longer: please allow 1-2 weeks. We'll give you a call to arrange a day that suits you.
