Bag of Trash

A small, dark green colored coin purse, with no designs on it, and a gold stud to hold the top flap in place. This bag can summon trash infinitely, and cannot have items be put inside. When opening the bag, whoever holds the bag will be able to state what trash they want to come out of the bag. The holder must truly believe that what they want is trash, so you couldn't summon money unless you truly believed that money is trash. Trash will come out of the bag as long as it is open, at a rate of 1 cubic square foot of trash per 18 seconds. Whenever you shut the bag, the flow of trash will stop, and will not stop the bag from being closed. The trash can only come out if it is pointed at the ground, or at an angle towards the ground. If you try to summon something that you don't truly believe is trash, then anything you do believe is trash will come out instead. The trash doesn't disappear, and will be in the state and condition you imagined it was in when you summoned it in the first place.
