Настоящий якорь — это не крюк, а полкилометра цепи на дне

An anchor doesn't hold a ship up by its own weight—and that's just the beginning. The real work is done by something you've never noticed: a chain lying on the seabed and an angle of just a few degrees. We'll explore how a ship's anchor actually works, why ships are torn from their moorings during storms, and how an anchor forgotten on the seabed can cut an entire country's internet cable. This new film, "Mechanics of the World," is about the invisible principles that hold the world together.
