It may look like a toy, but don’t be fooled by its looks. This is a machine that has been created from toys by Austin Granger, a University of Minnesota computer science student. He dedicated more than 250 hours of work and more than 100,000 K’Nex pieces to come up with this amazing creation that measures in at a height of more than 23 ft. It is currently displayed at The Works Museum.
“There are 8 tracks. The ball goes through 7 rocker switches to get to them, and they are evenly distributed so there is a 1 in 8 chance of any ball going down any track.”
In response to a question of whether a kid can knock it over, Austin responded, “The main support towers are incredibly strong, and are designed to withstand well over twice the load they would ever need to. During construction, I would set my large boxes of K’nex on the towers for easy access, as well as stress testing. Since this is in a public place, everything had to be designed to withstand whatever a little kid can throw at it.”
