Double-Barreled Shot-fun Shells

Although similar to my previous Shot-fun shell idea, these shells are designed to be used only in double barreled shotguns. Each shell contains a bottom weighted sheet of plastic with a powerful magnet at one corner and a parachute at the other. When fired, the magnets slap together, the sheets of plastic unfurl, and the parachutes open. The plastic sheets can come with a variety of messages, from the simple "Surprise!" to "Get off my property!" or "This is a robbery, everyone on the ground, now!"

Nothing gets your point across like a shotgun blast, except for a shotgun blast with your point across it.
