Another fun school holiday craft at our house was this Lego Marble Run! It is like a maze for a marble to roll through. To move the marble, you hold the tray and gently tilt it back and forth so that the marble rolls. It can be quite tricky to get it in the right spot to roll through some of the “doors”! Mr Happy (8) spent a quiet hour creating these toys for himself, then challenged the rest of us to get the marble through the maze. Then both he and Little Miss (10) spent some time seeing how fast they could do it.
He actually made two – a smaller one and a larger one. The smaller one is 16 x 16 little bumps, while the larger one is 32 x 32 bumps. The larger tray gave a lot more room for creating a tricky maze with some dead ends. He worked out that his small marbles needed corridors of 2 bumps width to be able to roll freely. The arched doorway is a trick – the marble won’t actually fit underneath it!
