The Magnetic Telescope

The story begins with Clark Kent and Lois Lane, along with the entire town, observing a scientist's (who resembles Captain Marvel (DC Comics)'s nemesis Doctor Sivana) demonstration of his magnetic telescope. A giant, u-shaped magnet connected to the telescope is pointed at a comet and turned on, drawing the comet towards the observers. Something goes wrong, however, and the comet crashes into the town, rolls through the streets, and then tumbles into the ocean nearby.
