Air tank cannons
I want to make a noisemaker air tank cannon by cutting off a tall O2 bottle.
I don't want to fire any bowling balls, just create a loud boom for New
Year, and 4th of July. Would it be better to use gunpowder or Acetylene/O2
mixture? I am considering of using an inflatable 99 cent ball to block the
barrel, just charge it, insert the ball, inflate, and fire. Leave it
hanging on a rack when not in use, and call it a bell, in case anyone should
investigate the sound of the report.
