Just type or paste any text(up to about 180 characters, including spaces) into the box above and click reverse, and get the obvious result. How could you use it you ask?  Well create an email message, in say Outlook express, copy that text and then send the email to a friend.  In the body of the email below the reversed text, put a link to this page and tell the person to go here and to paste the reversed text in the box and click the "Reverse Text" Button, to see what it says.  OR, you just instruct them to print out the email and try to read it reflected in a mirror.
