Description
Complete your marble run with the Gravitrax Color Swap expansion, a clever action block that gives the illusion of changing the color of a marble!
With a clever twist, the marble goes inside the block and comes out a different color. A magic trick that's easy to master, but sure to create a spectacular effect in a GraviTrax marble run! This action block is played with at least one Starter Set and can then be combined with any GraviTrax element.
The more children play, the more they'll be able to build elaborate circuits and produce amazing effects without their marbles leaving the tracks. Discover the laws of gravity, kinetics, and magnetism.
The box contains 1 Colour Swap action block, 3 marbles and 1 illustrated user guide.
