Did you know if you do a search in Google for [fun facts] or [i'm feeling curious] and possibly other variations, Google will show you a dynamic answer box at the top that pulls tidbits from their database?
Here is a picture of what I got when I searched for [fun facts]:
This box will randomly pull different facts from different web sites. It will ask the question, give the answer and then link to the source. The "Ask Another Question" button refreshes the search result to give a new fact.
The source of this is "i'm feeling curious" and not the "fun fact" because on refresh, the query changes to the "i'm feeling curious."
This seems like a brand new Google feature.
