This guy builds an awesome bronze cannon and shows us how he did it, in painstaking detail. So does he get accolades for his talent, ingenuity and perseverance? Of course not. The typical response is something like, "I wasted all this time watching through to the end, and then you didn't even shoot it?"
And if he had fired it, the most-upvoted comment would have been, "skip to 17:24 for the real action!"
