Tolbin's Trash Trick

You create a 2 inch radius portal to some unknown trash dimension. An object that is placed in the portal then vanishes and is lost forever in the trash realm. The spell  does not work on living creatures or on objects to large to pass through the portal. The bard Tolbin created this spell to discard unwanted poetry, song lyrics, and occasional evidence. Later in his career he created a spell to recall this trash, but never got it to work correctly.
