Get the Washer off the BoltI made my own "get the washer off the bolt" puzzle that was shown on your Reader Letters page two issues ago (Vol. 15, No. 5). I had fun trying it out on friends and came up with a couple variations to really confound people. I made a second puzzle where I didn't cut the bolt in half and welded the nut in place. Guys who thought they knew how the puzzle worked - screwing out the top half of the bolt - would really get frustrated. Another idea is to use a bolt with left-handed threads so that when they try to unscrew the top half of the bolt they just tighten it down more. (Alvin Reedy, Jesup, Iowa)
