(In some opinions also the waste of a lot of tractor parts?) This is almost unbelievable; see how all of the balls wind up in catcher cones. Read this first, then turn on your sound and watch.
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.
The Machine You Won't Believe.
