Watch a Ball Travel Through a Record-Breaking K'NEX Contraption

There are few things you can't construct with K'NEX. The plastic toys have been used to make a lawnmower, a chainsaw, and a computer, but this epic contraption may take the cake.

The 900-foot long structure was assembled by construction toy expert Austin Granger using 126,285 K'NEX pieces. In the video above, you can watch as a ball flies down illuminated roller coaster tracks, ascends a mini-elevator, and spirals down the mechanism's monstrous contoured funnel.

Granger has been tinkering with K'NEX toys since he was 5 years old. His previous claim to fame was "Clockwork," a Rube Goldberg-inspired device built in his bedroom using 40,000 pieces. Now, the 23-year-old University of Minnesota graduate has outdone himself by earning the Guinness World Record for the largest K'NEX ball contraption ever assembled. You can check out more of his impressive feats of toy construction at his YouTube channel.
