#3: Cotton Candy Gun
From: Killer Klowns from Outer Space
Used by: The Killer Klowns
Easily one of the most inventive guns ever to be featured in a movie, horror or otherwise, is the cotton candy guns wielded by the grotesque alien Klowns of Killer Klowns from Outer Space. When fired, the guns discharge a beam of electricity that covers the target in a flesh-melting cocoon of cotton candy. Trapped in the pink cocoon, the person inside slowly gelatinizes, bones and all, so the Killer Klowns can drink their juicy remains. Delicious!
