The classic Spacerail toy from the 80's has been recreated for your rolling pleasure.

Perhaps it's the mesmerizing perpetual motion as the balls zoom around loops and curves, only to be cranked corkscrew style up to the top for another high speed round. Or maybe it's the hours of assembly time spent fine-tuning each section of track to get the perfect run without the balls flying across the room.

Either way, the Spacerail series appeal is half geek based construction project and half satisfaction of watching your knotty marble coaster in action.

Of course you can build the exact structure shown in the instructions, but why not venture out and try your own mad creation with only the laws of physics as your limitation. This is a great gift for your friends of all ages...let the Spacerail journey begin!
