Talking about slingshot

[Finet Bidias]

When i was child we made slingshots by bending thick wire into the shape of Y. Then we cut a piece of rubber from a car tube. We use the slingshots to shoot stones onto the neighbour's roof or folders piece of papers to people.

Thanks for your message Finet. There is one sentence that is not clear:
folders piece of papers to people= Can you explain?
Thanks,
