Zipline

The Zipline is an Expansion component in a Gravitrax marble run. It allows a marble to travel along a clear plastic zipline and hit another marble at the end.

Function
The Zipline is made up of two platforms, a long plastic rod connecting them, and a marble in a harness that it able to travel across the rod. This marble is placed on the higher of the two platforms, and another marble is placed on the other. When a marble hits the top one, it rolls down the zipline and hits the bottom marble, causing it to roll away at a relatively high speed.

The Zipline is 4 tiles long, making it longer than Long Tracks. It does not matter which end tile is higher, as it will work either way. However, the marble holders in each end tile must be facing the plastic zipline (see the picture for the correct orientation).

This component comes unassembled, being made out of 9 separate pieces. Like the hammer, the marble that is used to create the Zipline is slightly larger than normal marbles. Unlike most components, the Zipline can also be partially disassembled after use to help it store more easily.

Obtaining
This Expansion component can only be found in its set, the Zipline Expansion.
