Watch Catapult (1970) Official Trailer

"A disk of wax soaked with lighter fluid is placed on one end of the balanced plywood. I run toward and Jump on the other end, catapulting the wax over my head in hopes of striking a strip of toilet paper, lighting and burning it. (the strips of toilet paper are strung in rows across the parking lot) The performance / film ends when all of the strips have caught fire." - David Askevold
