This is a ball machine I constructed which is completely elevated off the floor of my room on a 6.5 foot k'nex ceiling supported by 6 k'nex pillars. The machine consists of two tracks, the longest of which winds overhead a distance of over 70 feet! Each track contains its own motorized lift hill, meaning the path switcher rests at the end of the machine, rather than the beginning. This allows for the path switcher to use the chaotic motion of the k'nex balls to randomly switch a ball to one of the two paths, rather than every other path like in most k'nex ball machines. The machine contains about 15,000 pieces and took 3 weeks to build. The machine is still a work in progress, there are 2 more tracks in development.
Statistics: Build time - 3 weeks Height - 7.5 ft Length - 100 ft Number of supporting towers - 6 Number of bridges - 8 Number of paths - 2 Number of pieces - about 15,000 Number of unique elements - 9 Max number of balls - 25 Number of chain lift hooks - 12 Number of lifts - 2
