GraviTrax Action Pack Color Swap

Abracadabra, presto, chango your marble run just added some colourful, magical fun with the GraviTrax Action Pack Color Swap accessory!

The colour swap brings a new element of surprise into the GraviTrax world. As if by magic, the ball changes colour when it passes the stone. This can be prepared in two ways. Either by loading the stone with a ball at the beginning, or by installing it accordingly in the track. With the illusion of colour change, the colour swap provides a visual highlight. How often can the colour of the balls be changed during a run?
