cannon in production

Since people can't seem to get enough of this thing, here'e yet one more. This "device" incorporates an onboard propane fuel metering system, an 80,000 volt modified stungun with dual tandem electrodes for ignition. twin hand grips for stability, and a laser sight for accuracy to fire a tennis ball at 610 ft/s (416 MPH). Oh yeah, it's loud as hell and belches flames when fired. Questions and comments welcomed. If you use it, tell me where.
