Adding An Iframe - Problems

I am trying to grab the Iframe from here: http://ift.tt/1QWjr5k

The code is here:

    <iframe width=940 height=700            src="http://ift.tt/1QWjr5k" scrolling=no frameborder=0/>

but when I add it in the plain text editor on WP it does not work, just a huge white space.

Now I am thinking this is a problem with the Iframe itself? It has no tag, so maybe this is why?
