Launches cut bait to 150 yards. $100 in parts plus compressor.
Design details are in above video.
Geeky details (Physics performance specs) are in this blog post:
Bait Cannon for Bank Fishing
A old fashioned hair spray "spud gun" is cheaper, and no compressor needed. We used to use one to chum for sharks in the gulf. But that is a cool rig.
