The laws of physics go out the window with him.
In terms of adhering to physics, the super feats donít necessarily have to pass the scrutiny of a scientist or engineer. They just have to seem
plausible enough for the average person.
There was a scene in SIII
where Supes puts out a factory fire by freezing a lake and carrying the sheet of ice to the inferno - holding the large sheet by one end.
I submit that the silliness of this feat was apparent even to science dropouts. And you donít want to be making Supes look silly.
