Find out what happens when you put a box of Mentos in a bottle of Diet Coke. Watch a US senator make the mistake that lost him the race. It all started with one video of a trip to the zoo. Less than two years later, YouTube features 100 million videos, enjoys 20 million visitors each month, and has won Time magazine's Invention of the Year award. The founders of the Internet site have cashed in big, selling to Google for more than $1.65 billion.
