Above is officially the world’s largest K'NEX ball contraption.
The record-breaking machine—which features spirals, loops, ramps, elevators, and flashing LED lights—consists of exactly 126,285 K'NEX pieces.
Built by Austin Granger—a 23-year-old computer science major at the University of Minnesota—the toy marvel measures 912 feet in length. It took 16 months to complete.
The construction was commissioned by Brickmania Toyworks of Minneapolis, Minnesota. The company saw a YouTube video that Granger uploaded of his machine ”Clockwork,” another K'NEX contraption which took eight months to build and utilized over 40,000 pieces.
Granger, who has been playing with K‘NEX since he was five years old, says that every time he builds K’NEX, he learns more and more about the properties of K'NEX as a building and engineering material. “I just get a lot of satisfaction from finding problems and solving them myself,” Granger told Guinness World Records.
