Australia is infamous for its abundance of absurdly dangerous wildlife. From highly-venomous brown snakes and funnelweb spiders to giant saltwater crocodiles and great white sharks, nearly everything that slithers, crawls, or swims in the Land Down Under seems perfectly designed to inflict the most horrible death possible.

At the heart of every nuclear weapon lies the core or pit, a sphere of plutonium the size of a baseball and weighing around 6 kilograms.

In our previous video, The Surprisingly Long and Determined Effort to Create a Literal Flying Tank, we looked at how designers in the 1930s and 40s devoted a considerable amount of time and effort trying to combine two of the 20th Century’s most revolutionary weapons of war: the tank and the aeroplane.

Over the past 600 years swords became blunted, protective equipment increased, and rules steadily codified to produce a safe, formalized Olympic sport in which serious injuries are rare.
