Don’t Try This at Home
When I was a kid, I wanted to imitate a TV show where they did different challenges in an old prison fort. One challenge had the contestants jumping on a contraption that made cannonballs fly and hit some targets. I built my contraption with a wooden plank that I balanced on a rock like a seesaw.
Then I put a rock on one side and jumped on the other side. I didn’t realize what was going to happen until it was too late. The rock flew right in my face. Half my face was blue for quite some time after. Story credit: Reddit/Slimswede
