Catapult, aka Slingshot or "Bean Shooter"

[Highlander]

Cats, are at least one of the few un-restricted `weapons` that we can buy in the UK, so I am sure that most of us have at least one of them.

I also remember making my own on the farm when I was a kid, we all had them, and would use them against each other using plums or damsons,....the devils we were... lol

Of course for hunting we used ball bearings [ from wheel bearings ]....we got from the local garage
