A big weekend build for budding engineers. Children assemble a wooden marble run full of ramps, lifts and turns, then watch their creation in action as marbles race through the city. The build teaches gravity, momentum and simple machines in a way that feels like play, not homework. It takes real focus to complete, which makes finishing it all the more rewarding. A standout birthday gift and a great project for parents and kids to build together.
