Master Blaster

First you must find a room in which there is only one item of furniture. use this to store your finds. When you hide an item in it, booby-trap the single piece of furniture. Whenever you find another item just enter the room and press fire — it will automatically go behind the single piece of furniture. Alternatively select a certain type of furniture to use as a hiding place — say televisions. Always use a trap on it that can be remedied — if using a spring make sure that the wirecutters are available.
