I learned how to use a bolivian sling as a child.

It's a superior weapon vs the staff sling. With the arm wind-up, I can get more power. Also, it's something I can stick in my pocket.

But, the bolivian sling does take practice, coordination, and a bit of skill. Not something most ren-fair types have.

Oh, I forgot about staff slings.

Good Job OP.

Moar, want moar simple ancient machinery. Need input.

Stuffing a balloon with rusty nails and cat shit would make for some good ammo to launch at a leftist gathering.

What ren-fair nerds do when they're not at a ren-fair or making costumes.

I used to make those without the staff, just a loop you put around your wrist and hold the other string between thumb and forefinger. You could launch a rock the size of a tennis ball about 100 yards, and that was 12 year old me.
