Ravensburger Gravitrax action block color swap

Boost your GraviTrax circuits with this ingenious action block that will give the illusion of changing the color of a marble. Through a clever sleight of hand, the marble goes inside the block and comes out a different color. An easy magic trick to master, but one that is sure to create a spectacular effect in a GraviTrax marble run! This element is played with at least one Starter Set and can be combined with all GraviTrax products.
