Blog: Favourite YouTube Videos (Volume 155)

In this volume of my Favourite YouTube Videos, we lament the passing of small local video game zoos and celebrate just how cool modern engineering can be.

• First. Dave Bulmer, sings a song that makes him very happy. About Donkey Kong. And how he doesn't have a zoo any more. And it's a real song even!
• Next, Destin from Smarter Every Day discovers that the cupola shutters on the International Space Station work by turning a rod stuck through the side of the space station. You might think this would let all the air out, but, because engineering is cool, it doesn't.
• Finally, The Engineer Guy breaks down the way aluminum cans are manufactured, which is a very complex process for something that happens within a second or so.
