Discovery marble run color instructions

The runner up position goes to Magicfly's Marble Run Race Track. This 149-piece set uses translucent plastic for easy marble viewing and also comes with large and small bases for structural stability. Though you won't find a smartphone app to go with this one, the Magicfly kit does boast 4 motion-activated light-up marbles for added fun! Create an exciting marble track that runs automatically! You design the course, then watch as the steel balls race freely through the tracks and tunnels. It's a fun way to study the science behind speed! Explore the link between gravity and motino by customizing your very own 51-piece track. Create exciting twists, turns, and dips - then release the marbles and see your creation come alive!
