 Superman then pushes the death ray away from the base of the skyscraper and attempts to fight it back to the source, but the scientist increases the weapon's power, which also sends erratic “pulses” of energy Superman's way.However, Superman remains determined to fight it, persevering against the beam and punching out each pulse as they come, gradually pounding the beam back to the scientist's lab.Seeing that the beam has been overpowered, the horrified Mad Scientist increases power, but Superman uses that against him by twisting the barrel of the weapon into a knot, preventing the beam energy from escaping, and the buildup of pressure causes the machine to overheat and explode.
