Hint R4 - Ball Races In addition to roller coasters, K'NEX track is also excellent for creating K'NEX ball races, in which a ball races down the track rather than a Coaster car.
The most popular ball used for this purpose is the ball shown in the photo opposite, which can be built from any two of the K'NEX Ball half Red (90990), the K'NEX Ball half Yellow (90991) or the K'NEX Ball half Grey (90967). The completed ball is approx 45mm in diameter, and it has a hole through it, which fits any classic K'NEX rod. Alternatively, if you have one, the K'NEX Ball 50mm (22526) may be used for ball races.
A well-known example of a ball race is the K'NEX Big Ball factory, shown opposite. You can view some close-up photos of this model on the web page for the K'NEX Simple machines deluxe set.
