Scientific question: How did Clark use his heat vision to set off the fire sprinklers without melting the glass in the conference room door? When he knocked out the lightbulb in The Phoenix he burned holes in the lampshade. So, is it possible to make the fire sprinkler go off without melting a hole in the glass window of the door?
Maybe the sprinklers have a setting where they become operational if they are exposed to laser light. Or maybe he uses his vision to actually alter their internal mechanisms to set them off. Does not sound likely. On the other hand, maybe he did melt holes through the door, but no one noticed in the hubbub.
