Unbelievable the fine line between reality and imagination. Some of the ideas and implementations presented in the 20 weapons are of such a disturbing nature that they truly are creatively unique, even in a very morbid sense. I've seen other spooky weapons that Popsci has put in their publishings that are truly disturbing in nature also: autonomous/remote robot weaponry, sonic 'mental disturbance' weapons, and even electromagnetic pulse ordinance. Although I have to say the most disturbing of the 'spookiest weapons' I know of I learned thru 'Future Weapons', a show on the Military Channel, that featured a 'cannon-like' weapon that would fire bullets/grenades at the rate of 1,000,000/250,000 rounds/MINUTE. The 'Metal Storm' listed as one of 'The World's Spookiest Weapons' actually uses this same (or relative) ignition technology. How would you stop that rate of fire and destructive energy? I have to say I appreciate and respect the efforts of Popular Science to bring these new ideas and technologies to the forefront, thanks :) Michael D Lewis Science Manager - RD g_K Technologies gktech.mdlewis@gmail.com
