Remove Extra White Space

There is some extra white space right above the "Start Slideshow>" button on our post pages on our website Recaplet.com ... For example, if you go to http://www.recaplet.com/incredible-pain-relief-putting-clothespin-ear-just-5-seconds/ you will see extra white space between the ad unit above the "Start Slideshow>" button and the button itself. I'm attaching a screenshot with the white space marked with a big red circle.

Can you please tell me how to remove this white space?

Thanks!
