LONDON – For most people, having their iPhone crushed is the ultimate nightmare. Not for scientists at the University of Plymouth, Cult of Mac reported. The UK university put an iPhone into a high-powered blender to discover what chemical elements a handset is made up of. There’s a video too, if does cause you too much pain to watch. The video does a good job of breaking down the precise quantities of elements which go into a smartphone. Where it gets particularly interesting, however, is looking at this figure in the context of the 1.4 billion mobile phones produced each year, Among other astonishing figures, that includes 52 tons of gold, 131 tons of silver, and a mind-boggling 10.2 kilotons of chromium.
