Runescape New Feature Game drop room

I found this room in Falador north east of the Fally bank there is a new room that is quite fun to join in. This Room is where the Balloon drops and the Dancing knight minigames are located. What you need to do to play this minigame is to place an item in the tresure box east of the room then. pull the lever slightly north of it then The items will be collected in the room in random locations. Quite a nice minigame too :)
