In Australia there is a well known traditional Aboriginal weapon called a boomerang. This works perfectly well, but as always modern means of production can bring improvements.
In this case that improvement is the Ice-erang.
The Ice-erang is a boomerang made entirely from ice. It comes out of its two part mould perfectly formed and aerodynamically ready for throwing, and there is no need to worry about catching it on its return journey or retrieving it. If it goes astray, it will quickly melt away, and probably won't last more than one throw anyway in the scorching heat of an Australian outback location.
Once you have dispatched one Ice-erang, simply pop out another one from the dozens you have pre-made, and stored in your cold box ready to launch.-- xenzag, Sep 04 2014 looks baked in this game..? http://terraria.gam...a.com/Ice_Boomerang [xandram, Sep 05 2014] Pointless transfer of modern tech to ancient tech [+]-- the porpoise, Sep 04 2014 Projectile weapon [+].-- 8th of 7, Sep 04 2014 We might expect this invention to last a bit longer in various places, in the winter time.-- Vernon, Sep 05 2014 Add some sawdust; pykrete-erang.-- mitxela, Sep 05 2014 And for tonight's performance: kangaroo on ice [+]-- 4and20, Sep 05 2014 random, halfbakery
