Mozilla used to use a fantastic little tool called X-Ray Goggles that let you view and customize the code behind any web page. They shut it down a couple of years back and considering that then Ive been advising that people just
use Chromes inspect tool to see the code behind a website. I even consisted of that in
my weekly newsletter today. Today I discovered that
Mouse.org offers its own
X-Ray Goggles tool for customizing the code and seeing behind a page..

Mouse.orgs X-Ray Goggles tool lets you see the code behind any web page and change that code to show anything that you desire in location of the original text and images. After you have made the modifications you can release a local copy of the websites. In this short video I offer a demonstration of how Mouse.orgs X-Ray Goggles tool works..

Applications for Education.
Mouse.orgs X-Ray Goggles offers a great way for trainees to see how the code of a web page works.

As I discussed in the video, you might use X-Ray Goggles to change an article online to make it a satire story. Then print the page and give it to your students to try to determine the satire components of the story.
