Forgotten Phlebotinum: Difference between revisions

** The [[Silver Age]] had ''tons'' of Forgotten Phlebotinum. FoFor example, there is ''Action Comics'' #252, an issue otherwise better known for being Supergirl's first appearance. In the lead-in story, though, Superman is being menaced by kryptonite, and he escapes by melting it with his heat vision, at which point he learns the liquid kryptonite is no longer harmful. (In a real head against wall moment, he even says that it's because when items change their state, they lose other properties, like how ice, when it melts into water, [[Critical Research Failure|stops being cold]]. Of course, Superman forgets that liquid kryptonite is harmless to him thereafter, and in fact, liquid ''and gaseous'' kryptonite are shown being harmful to him in later stories. [[It Only Works Once|So maybe he found the only chunk of kryptonite in the universe that would be harmless to him if it were liquid.]]
