Basically using the Vending machine if you put the same item in the cost and result slots, then add the item to input and have a second of that item in your inventory it dupes it and gives an item to your inventory and moves the input item to the output giving you an extra item. This can be done multiplicative if you increase the item count in the cost and result window, granted you have enough of that one item.
