iframe wikipedia article without the wrapper

Question

I want to embed a wikipedia article into a page but I don't want all the wrapper (navigation, etc.) that sits around the articles. I saw it done here: http://www.dayah.com/periodic/. Click on an element and the iframe is displayed and links to the article only (no wrapper). So how'd they do that? Seems like JavaScript handles showing the iframe and constructing the href but after browsing the pages javascript (http://www.dayah.com/periodic/Script/interactivity.js) I still can't figure out how the url is built. Thanks.

The periodic table example loads the printer-friendly version of the wiki artice into an iframe. http://en.wikipedia.org/wiki/Potasium?printable=yes

it's done in function click_wiki(e) (line 534, interactivity.js)

var article = el.childNodes[0].childNodes[n_name].innerHTML;
...
window.frames["WikiFrame"].location.replace("http://" + language + ".wikipedia.org/w/index.php?title=" + encodeURIComponent(article) + "&printable=yes");
