Walking with Superman: Day 248

Clark Kent and Lois Lane have come to Niagara Falls, New York, to take in the simple majesty of North America's most powerful waterfall. And it becomes a whole different sort of powerful when Dr. Alchemy uses his Philosopher's Stone to transmute the water of the falls into concentrated hydrofluoric acid! Superman must spring into action to save the Maid of the Mist and the other onlookers and tourists from certain death in the corrosive fluid, which leaves the task of defeating Dr. Alchemy to intrepid reporter Lois Lane!
