Hang the 10 Dropping Spider Prop on your front porch or in the doorway to your Halloween party to give guests and trick-or-treaters a jump scare! While this black spider isn't frightening or gory in and of itself, the fact that it suddenly drops down from the ceiling to say hello makes it as good for scaring as any other horror prop. It's covered in an all-black fabric and has four straight legs on either side of its body. Two white ovals act as eyes on this black arachnid.
