6 meters of track for marbles to be launched at maximum speed thanks to a special "rocket shoots balls".
The "rotating atomic hammer" gives extra power to the balls which, at surprising speed, reach a spectacular round of death.
The suspended track can be built in many different ways, following the instructions included in the package, or inventing new routes.
The rocket shoots rocket has a particular system inside that triggers a thrust such as to allow the marble to make evolutions uphill without losing speed.
