Marble Run strength and stability

A problem that children sometimes encounter when designing their own Marble Runs for the first time is how to make their Marble Run structure really strong and stable.

There are a number of ways to achieve this, such as:
  • Design your structure as a tower with a triangular cross-section, as shown in the photo.


  • To achieve maximum strength, make sure you have at least two bridge or track sections going across each side of the tower. This will help to keep the columns vertical.


  • To achieve maximum stability, place the Marble Run on a level, smooth surface (preferably not thick carpet). This is particularly important when using the Spiral, as unevenness in the surface may prevent the marble from running right around the spiral.
