Taken for a short ride in Virgin's glass-bottom jet

A glass-bottomed plane by Virgin Atlantic, a new Google search that allowed you to search and sniff smells and a plan to milk the feral cows of Sai Kung, were just some of the pranks floating around on April Fools' Day yesterday.

In the true spirit of April 1, people all over Hong Kong were made fools of ... at least for a few seconds with a variety of jokes which were mostly aimed at internet users.

Google excelled by claiming to have launched Google Nose: a new addition to the search engine which allowed users to search its "Aromabase" of 15 million Scentibytes for smells.

The prank invited the gullible to edge close to their screens and take a sniff of beer, wet dog, locker room and garlic breath.

Google Earth also announced it had added a new treasure hunt mode, inviting people to help them solve a mystery contained in recently discovered treasure maps belonging to the legendary pirate Captain Kidd.

Google-owned YouTube was ahead of the game, releasing a three-minute video clip on Sunday saying the site would close down at midnight for a decade and that its aim over the last eight years had been to find the world's greatest video.
