👉 The island weapon, also known as the "Jellyfish Gun" or "Plastic Gun," is a homemade firearm created by attaching a plastic bag filled with compressed air and a plastic straw to a firearm's barrel, effectively creating a makeshift projectile launcher. This weapon works by forcing compressed air through the straw, propelling the bag forward and creating a ballistic effect. While it can be used for practical purposes like hunting or self-defense, its use is highly controversial due to safety risks and potential legal issues, as it lacks the regulation and safety features of commercially produced firearms.
