Turn up your sound for this one; read first, then watch.
This is almost unbelievable....
See how all 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 machines components came from
JOHN DEERE Industries and Irrigation Equipment of Bancroft, Iowa.
YES, farm equipment!

It took the team a combined 13,029 hours 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 and is already slated to be donated to the Smithsonian.
