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.
