Roomarang

A Roomarang is a variant on a Boomerang that is made of foam so that it can be used indoors without risking injury or damage to the building, hence the name "room"arang. A roomarang is shaped like a helicopter blade so that when it turns clockwise it generates lift. In order to throw the roomarang the user gives it clockwise rotation at the same time as throwing it outwards, and it usually travels in a full circle around the room and then returns to the thrower. The roomarang is mainly for relieving stress, such as when on the job, and can be used safely in an office, so long as it isn't intentionally thrown at another object.
