One of the original Air Cannons' Twister 325 (aircannons.com). Cannon works
great, T-shirts, foam cups, stuffed animals, you decide. CO2 cartridges can be
purchased from aircannons.com or retailer of your choice. Best air cannons in
the business, they supply all the major sports teams and corporate events. This
is a collector's item. Rarely do you see a used one for sale. I've seen a video
where a guy converts it into a flamethrower with minimal effort and cost!!!
