I Want a Raygun

Originally designed by a NY'er for his obsessively geekish Halloween costume, these Buck Rogers-esque faux pistols're soldered/screwed together w/ 1lb of metal and wood, sport a toggle switch that "lets you alternate between 'useless' and 'devastating' modes", and're carbon-scored on the muzzle for that realistic I've-got-a-raygun-and-I'm-not-afraid-to-pretend-to-use-it look.
