I am the master at crumpling paper...Ever since like 7 I would take paper out of recycling bins and shoot them in the trashcan....or nail ppl in the tooth/nuts...I insisted they change the "flat paper in recycle bin" rule but they want to be stubborn...Also when I was younger we would have paper ball battles on the bus/class/cafeteria/home

And that looks really fragile...so you can't really battle with them which is what first came to mind
