You can extract your own DNA with drinking water, salt, dish soap, alcohol, food coloring, and your own spit! This NOVA/PBS-made video shows you how.
I've been writing about DNA for more than a decade, and I just realised that until this video, I've never actually seen DNA. And there it is, in the form of a white string in a plastic cup. Pretty freaking neato.
Learning anything more about your DNA requires a more complicated process of sequencing and analysation and at least $100 bucks. But in lieu of that, the opportunity to gaze upon one's genetic make up seems rather satisfying not to mention entertaining! [YouTube]
