Google Legends

Where do the legends of the great and powerful monster GOOGLE come from.
I work in a lyceum. A chemistry teacher is asking me to test in my office. I ask a natural question.
- What will you test in?
- In Google?
- o_o
Invites, therefore, the luminary of the science of children in the office and says to launch Google.
further next.
- In the search bar, write chemistry testing.
- In the list that appears, select the second link.
- And we are testing.
Indeed, great and powerful GUGL.
