One of my brothers enjoyed playing with Rattlesnakes. He'd catch one under a bucket, then scoop the lid under the bottom of the bucket, then all the brothers would stand around and throw pieces of gravel in the bucket to make it hiss. My Mother, just arriving home from the family business, nearly had a heart attack.
Another fun thing we did was take paint buckets and attach them to each corner of the clothes line (one of those clothes lines that looks like a wind blow umbrella that twirls around) put the younger kids in two of the buckets and pull it around by a chain, sending them straight out sideways. Lots of fun accidents with that one.
BB guns, of course.
We also enjoyed jumping off the peak of the roof into the snow pile below; putting each other in a metal trash barrel and rolling down the hill in it; shooting out streetlights; and setting field fires while burning insects with a magnifying glass. Yes, I am a former arsonist.
Our parents didn't buy us toys too often, so we made up our own fun. My Mother was a book worm and had her nose in the books alot of times, so she pretty much let us terrorize the neighborhood, as long as we weren't bugging her. We had more than one neighbor move out from next door.. hehehhe.
