Here are seven interesting documentary-type videos found on YouTube:

You’ve probably heard that Geek Squad technicians snoop around on customers’ hard drives and copy photos and other files for their own use. But have you also heard that they overcharge ridiculously for simple little repairs? Have a look below:

The metro bridge over the river Tyne at Newcastle, UK, was recently outfitted with LED lights that are programmed to never shine in the same sequence. The result is a mesmerizing light show that goes on and on:

Bill Crosby did a documentary in 1968 called “A Boy Like Me”, where he pointed out racial inequalities between black and white children. But he did it in such a poignant way that it’s really, really hard to miss the point. Watch this segment in its entirety, it’s only 3:28 minutes long.

The Falkirk Wheel is an advanced bridge for boats. It connects two bodies of water that are separated by a great height in a very interesting way:

Whether you may or may not agree with this first part of the documentary entitled “The Great Global Warming Swindle” (the other parts can be found on YouTube as well), I think you’ll realize it raises some interesting and valid points. I watched the entire documentary, and if you’ve got the time, I would encourage you to do the same.

The next video is pretty geeky in its approach, but it was made to demonstrate how IT security works for non-techies, and it does a great job of it. It’s entertaining, so you won’t get bored, either.

This last video is controversial, and I don’t know what to make of it. It’s actual news footage aired immediately after the crash of United Flight 93. It shows the crash site and surrounding areas, but the strange thing is that the place looks very much unlike a plane crash site. There are no large pieces of fuselage, no bodies, nothing — just a small hole in the ground, and that’s what makes it unusual. It just doesn’t look like a plane crashed there at all.
