Grimm's Assembly Ball Run from Oskar's Wooden Ark can be easily built by kiddos (or with a little help from mum and dad for the younger ones). Children can freely sort the colours as they like. It can also be reassembled to try a different colour set-up.
Once built, it functions as a double spiral run where kids can have marble races, try marbles of different sizes and materials, and listen to the beautiful sounds the bell marbles produce.
To make your ball run even more fun and exciting, our Grimm's Wooden Marbles would be a perfect addition!
An overview of the different Marble and Ball Runs available can be found in our blog post The Ultimate Marble Run Play Guide.
