Traditionally, most boomerangs used by aboriginal groups in Australia were 'non-returning'. These weapons, sometimes called "throwsticks" or "kylies", were used for hunting a variety of prey, from kangaroos to parrots; at a range of about 100 metres (330 ft), a 2-kg (4.4 lb) non-returning boomerang could inflict mortal injury to a large animal.[1] A throwstick thrown nearly horizontally may fly in a nearly straight path and could fell a kangaroo on impact to the legs or knees, while the long-necked emu could be killed by a blow to the neck.[citation needed] Hooked non-returning boomerangs, known as "beaked kylies", used in northern Central Australia, have been claimed to kill multiple birds when thrown into a dense flock. Throwsticks are used as multi-purpose tools by today's aboriginal peoples, and besides throwing could be wielded as clubs, used for digging, used to start friction fires, and are sonorous when two are struck together.

the rest is cut into two, for the boomerang launcher

Step 2: How to Play

this is a boomerang that cannot go back, play for the furthest race, or to drop a target (such as used paper which is clotted as a target)

use the remainder of the bundle in half, one to put the boomerang on and one to make it fly

place the boomerang on the launcher so that it can be hit, hold the mica in one corner until it has a curve to have a moment to hit, slide until the mica hits the boomerang
