Intro: K'nex Ball Contraption- the Prize
This is our largest and most complex ball contraption to date. It took nine months to build, has multiple unique elements, two lifts and sixteen different paths. It took approximately 31,000 pieces to constuct and over 100 lbs. of K'nex. Individual photos of the elements can be posted. Please comment and let me know which elements you would like to see up close.
