Turn off the main light, release a ball at the top of the track and watch it shoot down like a comet. The Connetix Ball Run Galaxy Pack is a magnetic marble run with glitter tiles in blue, purple, black and silver, and two light balls that make the glitter sparkle as they roll through the transparent tubes. During the day you build under a starry sky, in the evening it becomes a light show with a route of your own design.
Building works just like with any Connetix marble run: you set up a tower of magnetic tiles, hang U-pieces, curves and slides on it, and adjust it until the ball lands neatly in the bowl at the bottom. Whatever doesn't work, you fix with one hand, and so children play with gravity, speed and balance without a manual telling them how it should be. A tip from us: build the track on a Connetix building board, then the base won't slide away and you can move the entire structure in one go. The Galaxy tiles also click onto all other Connetix sets, so an existing marble run gets a little piece of the universe added to it.
