There are at least two types of Australian boomerangs. One, a heavier version, is not designed to return. It simply goes out a fair distance and strikes hard whatever it’s aimed at. The other type returns. Years ago, some of us would use a router and make 2” oblong slots in either end of a returning boomerang. Then, we’d tape miniature chemical light sticks in the slots and throw the boomerang at night. The result was amazing.

Your boomerang had Wi-Fi?
