When you sleep, you grow by about 8mm but shrink again in the morning!!!!

However, this growth is just temporary, the next day you shrink back to your former height.The reason is that your cartilage discs are squeezed like sponges by the force of gravity when you stand or sit.

CAPTCHA is an acronym for 'Completely Automated Public Turing test to tell Computers and Humans Apart'!

CAPTCHA is a computer challenge-response test used to determine whether the user is human or computer robot.The process usually involves a computer asking a user to complete a simple test which the computer is able to grade.

These tests are designed to be easy for a computer to generate but difficult for a computer to solve, but again easy for a human. They are not always easy for humans, though. If a correct solution is received, it can be presumed to have been entered by a human.

The default wall paper of Windows XP desktop is a real picture of a real location with no digital enchantments!!!!

You may be familiar with the Windows XP background. It shows a beautiful green field underneath a crystal blue sky. A few clouds are scattered across the screen. The background is named "Bliss" and is an actual photo taken in Sonoma County, California.

Professional photographer Charles O'Rear took the photo for the digital design company HighTurn. Despite it's unreal appearance, O'Rear maintains that the photograph was not digitally enhanced or manipulated in any way. The image was captured from the side of the highway.

A pound of feathers actually weighs more than a pound of gold!!!!

Here is the reason...

Gold is universally weighed using a different measurement system than most other materials. It is weighed using the troy system, and troy ounces.

This system is measured so that 12 troy ounces makes up 5760 grains to the pound, while the common measurement for feathers would make them equal to 7000 grains to the pound.

Thus, a standard pound of feathers technically weighs more than a pound of gold!

Clocks used to be made out of candles!!!!

A candle clock is a thin candle with consistently spaced markings (usually with numbers), that when burned, indicate the passage of periods of time. While no longer used today, candle clocks provided an effective way to tell time indoors, at night, or on a cloudy day.

A candle clock could be easily transformed into a timer by sticking a heavy nail into the candle at the mark indicating the desired interval. When the wax surrounding the nail melts, the nail clatters onto a plate below.

Astronauts on the International Space Station see around 15 sunrises and sunsets every day.

The International Space Station orbits about 354 kilometers above the Earth and travels at approximately 27,700 km/hr, so it takes about 92 minutes to circle the Earth once. For this reason, every 45 minutes the astronauts on-board see a sunrise or a sunset, with a total of 15 – 16 sightings of the sun "rising" and "setting" every single day.

Space sunsets are said to be even more spectacular than any that can be viewed here on Earth. This is because from space you can see all the detail within each of the Earth’s atmospheres in breathtaking bands of pink, orange and blue!

Newborn Babies Will Cry Without Tears Until They are Several Weeks Old !!!!

Newborn babies are incapable of producing actual tears because their tear ducts haven’t fully formed yet. In many cases, their underdeveloped tear ducts can also be clogged with amniotic fluid for a time after birth.

Every baby is born with basal tearing, which means that their tear ducts create enough moisture only to keep the eyes wet and healthy. Proper tears in a baby begin around 3 to 12 weeks old. In some cases, it will take even longer – up to the first several months of a baby’s life.

Story behind Tea bags Invention!!!!

Thomas Sullivan actually invented tea bags by mistake. In 1908, he was a tea merchant in New York city and looking for an easy way to send tea samples to his customers.

He found that it was more convenient to send the samples in small silken bags rather than boxes. Some of his customers assumed these bags should be used like an infuser and put them right in their cup.

These customers told Sullivan that the silk was too fine so he developed bags made out of a gauze material.

Tea bags Commercial production was started in the 1920s.
