Sheaf toss is a traditional Scottish agricultural sport event originally contested at country fairs. A pitchfork is used to hurl a burlap bag stuffed with straw over a horizontal bar above the competitor's head. Typical weight for the bag is 16 pounds (about 7 kg). Three chances are given to each competitor to cleanly go over the bar, without touching it. After all challengers have made their attempts, the bar is raised and all successful competitors move on to the new height. This continues until all but one athlete is eliminated.
