Returning Australian Boomerangs
Boomerangs were the world's first heavier than air flying machines, used most famously by the Australian Aborigines, but also found in other ancient cultures in Egypt, stone age Europe and the Indian Sub Continent. No-one knows how they were first invented and even though they look simple, they use a very complex combination of physics and aerodynamics to perform their amazing returning flights. Most importantly... they are FUN!
