Hey, the Tennis Ball Cannons were called "Goose Guns" in Indiana. We also launched Dixie Cups full of little green apples, too.
In a safe, controlled manner, of course.
Bwahahahahahhaaa
I happened to see, in a home improvement store, that they were selling replacement garden-shears blades with 2 holes drilled in them for mounting purposes. Kinda sharp and pointy, they were.
On a nearby rack, there were some long, wooden replacement handles that also had 2 holes in them. In nearly the same place. How convenient.
The small-hardware section may or may not have had some 2.5inch lag bolts, lock washers, and nuts for $1.59...
Nearby were some neat Viking-looking tools sometimes called Bill Hooks, or Ditch Blades. (Whoooosh! is the sound they make when you accidentally cut open a 25 pund bag of Ortho Lawn Fertillizer, BTW)
Now, If I could find some old, worn out tires, some heavy-duty tin snips, and some ultra-heavy duty cable ties or somesuch, I might be able to make "a festive, decorative vest for my next costume party, officer."
If I were concerned about the pokey little sharp steel belts on the edges of the tires abrading my neck and arms, I might look for some of that grey colored plastic-foamy slip-on pipe insulation to glue or rivet on, but I'm just speculating, y'know...
