Magnet cannon

The Magnetic Cannon is an expansion component in a Gravitrax marble run. It functions similarly to the hammer, speeding up a marble out of one side.

Function
The Magnetic Cannon requires at least three marbles to function properly. Two marbles are placed on one end of the central piece, and it is triggered when another marble hits the other end. When this happens, the final marble on the other side of the wall is launched away from the Magnetic Cannon at a very high speed, much faster than with the Hammer. In fact, it propels it so fast that the marble can even go uphill after it is launched.

The Magnetic Cannon still works with any number of marbles stacked on the outgoing side, but only fires the final one. After a marble has been fired, it must be reset to its original position in order to function again.

If there is a 60° curve too close to the outgoing side, the marble that is launched has a tendency to fly off the track. Therefore, it is recommended to launch the marble onto a hill to slow it down before a sharp curve.

Obtaining
Even though it is classified as an extension, it is actually available in three different Gravitrax sets - the Starter Set, the Starter Set XXL, and the Magnetic Cannon Extension. Each contains only one Magnetic Cannon component, and they all come fully assembled.
