#5 The Phaser Gun
The phaser gun comes to us courtesy of Ionatron, which makes what it calls "directed energy weapons." According to the company's Website, its devices produce "man-made lightning" to disable people or vehicles that threaten our security." Basically, it's a short pulse laser that can be directed at a target with ferocious intensity. The company also notes that the gun is available in lethal and non-lethal versions.
