I see it all the time on social networks, someone will post a pic of them spark testing a piece of steel and ask, "Is this good". Got me to thinking, so I came up with this video set up as a game. I test 12 pieces of steel and the viewer guesses what they are. Answers are at the end. Ironically, I posted this video to some of those pages and while that newb asking will get 50 opinions I have gotten almost none. Those "experts" disappeared. lol. Of the ones that have taken the challenge, 3 has been the highest number gotten right.
Rule #10; "I can make that" translates to; "I'm to cheap to buy it new."
