Avid K’nex specialist Austron claims to have built the world’s largest K’next ball machine which is housed at The Works Museum in Bloomington, Minnesota. <br /> <br />And no one dares to debate his claim as the machine is truly colossal, standing over 23 feet tall and containing over 100,000 pieces. <br /> <br />“It takes 3 and a half minutes for a ball to climb to the top of the tallest tower.” <br /> <br />His fingers must be killing him.
