Since it's subjective, it doesn't have to be cool in the sense of "Grim reaper on a mountain playing an electric guitar".

Failure to properly use this trope can cause collision damage with walls. Note also that different opinions on what is "cool" create the most arguments over this. Note that you only get to invoke the Rule of Cool if the end product is, in fact, cool. The Second Law of Thermodynamics is third and a mention has to go to the laws of relativity, which prevent us from attaining Faster-Than-Light Travel and going to a distant planet in just a few hours. Of scientific laws that this trope circumvents, the third law of motion is probably the most frequently revoked, with the Square-Cube Law probably a close second.
