“Clockwork” is the Coolest K’Nex Machine We’ve Seen Yet [Video]

Here’s a riddle for you: What takes 8 months to create, has over 450 feet of track, includes over 40,000 K’Nex pieces, 8 motors, 5 lifts, 21 distinct paths, and a computer-controlled crane? Well, in this case, the answer is “Clockwork,” a giant K’Nex ball machine created by intrepid YouTube user austron. This is apparently their fifth major ball machine, as well as the largest, most complex K’Nex structure they have made. Check the video out for the wild ride, with an illuminated finish.
