Example Input: Article: Do you want to write your password down so that no one can see it, or do you want to send someone a secret message? Knowing how to make an invisible ink message will have you feeling like a secret agent in no time. These are instructions for making invisible ink using baking soda. Difficulty: Easy Time required: A few minutes What you need: Baking soda, Paper, Water, Light bulb, Paintbrush, Measuring cup, Purple grape juice Here's how: There are at least two methods of using baking soda as invisible ink. Mix equal amounts of water and baking soda. Use a paintbrush to write a message onto white paper, using the baking soda solution as "ink". Allow the ink to dry. One way to read the message is to hold the paper up to a heat source, such as a light bulb. The baking soda will cause the writing in the paper to turn brown. The second way to read the message is to paint over the paper with purple grape juice. The message will appear in a different color1. Tips: If you are using the heating method, avoid burning the paper. Baking soda and grape juice react in an acid-base reaction, producing a color1 change in the paper. Grape juice concentrate results in a more visible color1 change than regular grape juice.

Example Input: Article: Face book, the world's biggest social networking site, is celebrating its sixth birthday. The site's founder, Mark Zuckergerg, states that Face book will continue to work as hard as it has worked in the last six years in order to stay the web's number one communication site. The company started in a dorm room in 2004. Today it has 150 million active users, more than the 130 million of its competitor MySpace. Face book set itself apart from other social networking sites because you can communicate with people you really know and trust. Before, most people didn't want to share their real identities online. Face book has given people a safe and trusted environment for people to interact online. It has changed the way people view the world. A friend from any country is only a few clicks away. It was back in February 2004 when Zuckerberg started "the Face book" from a Harvard student's room. The aim was to help students get in touch with each other over the Internet. Within 24 hours over a thousand students had signed up and soon after that the network spread out to other universities. By 2005 a research study showed that about 85% of the students in the network had a Face book account. Another survey showed that Face book was almost as important as an iPod. At the end of 2005 Face book came to the UK. And up to today the site has been translated into 35 languages. Six years after its start, Face book has escaped the universities and colleges. More than half of its users are not at college any more and the fastest growing group are the 30 to 40-year-olds. Every day 15 million users update their profiles to tell their friends and the world what's happening to them. They also share photos, upload videos, chat, make friends, join groups and simply have fun.
