Wonder wheel in Google

I am doing a wonderful course to become an Internet Superuser at http://www.getsmarter.co.za/ and learning so much!

To find the wonder wheel in Google work from a Google search page, i.e. type a search term into that text box, and hit the "search" button to see a page with search results.

Now look at the top left of your search page, just under the search bar, you should see a link called "+ show options"
That will open the "options side bar" inside your browser view, and you should see the option for Wonder Wheel down near the bottom of the list.

Play with that! Wow.
