LEGO Video of the Week – September 24, 2012 – Great Ball Contraption (GBC)

This week’s video of the week is aptly titled “Great Ball Contraption

It is exactly what it sounds like a – massive contraption that moves 500 balls (1 ball a second) around 17 different modules.  It took over 600 hours to build.
