Marble Building Toys & Runs

There's something about a marble run - create an infrastructure, drop a marble somewhere in it, and watch it whirl, swirl, drop, and make its way through. Wooden marble runs generally consist of blocks with holes and grooves - marbles run along these until they find a hole, where they drop through and continue their journey. Plastic marble runs can have vortices (basically large funnels) that create exciting swirling action. Quadrilla marble sets are wooden but have some of the most sophisticated engineering around - vortices, levers, and more! Marble runs are fabulous teachers of mechanics and physics. Some sets have pieces that can create unpredictable outcomes - what happens next depends on what happened last. The ability to set the marble run up in different ways allows for creative experimentation that never ends.
