This is almost unbelievable. See how all of the balls wind up in catcher cones.
This incredible machine was built as a collaborative effort between the Robert M. Trammell Music Conservatory and the Sharon Wick School of Engineering at the University of Iowa . Amazingly, 97% of the machine's components came from John Deere (tractor) Industries and Irrigation Equipment of Bancroft , Iowa .. Yes, farm equipment!
It took the team a combined 13,029 hours (6.26 years) of set-up, alignment, calibration, and tuning before filming this video but as you can see, it was WELL worth the effort.
It is now on display in the Matthew Gerhard Alumni Hall at the University of Iowa and is already slated to be donated to the Smithsonian.
