Coltan

Did you ever hear this word before? I did not. Till today when I came across a link to a short video called 'Blood Coltan' on Facebook. I followed the link and watched the video. This is not a very pleasant experience, I admit. Then dug in for more info on internet, YouTube in particular and found 'Blood Coltan' divided into six parts for easier downloading. Below you can watch all six of them or you can follow the link I posted above and see there.
