Don't want vermin stealing from your bird feeder? Then do what this family did, which is to motorize the bottom of it, should something heavier than a bird (e.g. a squirrel) infiltrate. Watch what happens to the unsuspecting critter inside.
Update: Via an email from a reader, more information... the bird feeder is called the Yankee Flipper. You can read more about it—and order one for your own yard!—by visiting the manufacturers' web site.
