Sneak into the nearest rail valley and leave a penny on the tracks. Then run back up the hill and do something else for three hours. In that time, one of the mile-long freight trains that pass through your town will spread the penny like butter over the hot steel. When the train is gone, go back down and you'll find a flat, oval-shaped piece of copper in the same spot you left the penny. The piece of copper is useless, but it's satisfying to be responsible for squishing hard metal.
Look out for the rail bull!
