Fulgurite - What happens when lightning hit on sand?

HOLLOW GLASS TUBE.
FULGURITE
When lightning hits on quartzose sand, it leads to the formation of natural hollow glass tubes. The quartzose sand mainly contains silica. As lightning hits on sand, the temperature raises to 3270 degree Fahrenheit which results in the instantaneous melting of silica content in the soil on a conductive surface and fuses grains together. The cooled product thus formed is Fulgurite. The process occurs in a time gap of one second. The huge amount of electric charge from lightning is the main reason behind the formation of hollow glass tubes. The glass thus formed is called Lechatelierite. These glass tubes can also be formed by a heavy meteorite impact or a volcanic eruption. 

Like this phenomena, these glass tubes can be formed when a high electric current cable break into a conductive surface with sand beneath.

However the tubes formed are different in its length and diameter. The biggest tube is formed in north Florida  USA which had 4.9 meters as its length. Their color and nature depends upon the composition and mixture of sand.

Stephen Wiltshire's power of brain

Today i am going to introduce an incredible man called "Stephen Wiltshire". A person with neurological defect is doing this great work of drawing a whole city with the power of his subconscious mind from a single look at it. Do you guys believe in this fact?
Sometime the truth is so strange like this.

Stephen Wiltshire

Stephen wiltshire is an architectural artist in britain. At the age of three, he was found with autism. He is well-known all over the world for his great amazing drawing works. Wiltshire have a very special ability that he can look at a subjects once and then draw an accurate, perfect and clear picture of it. One of his well-known work in his career is that, he constantly draw a detailed and perfect picture of the 4 square miles of london after a single 20 minute helicopter ride over the city.

The drawing of 305 square miles of New York city is also based on 20 minute helicopter ride over the city. His amazing 18 feet panoramic drawing of the city had gained the attention of whole world. He always used listen to music while he works.

At the childhood itself, he was very interested in drawing. Then he gradually starts to communicate through his art. He attended city and guilds of london art school. Later he was awarded with the position of member of the order of british empire(MBE) for his great works.

World's Smallest Horse-Einstein

Hello guys meet this Amazing Horse. This little horse become a record holder and come to the position of smallest horse the world ever had viewed.

Einstein




This is the world's smallest horse named Einstein. The horse is about 14 inch high and have an amazing weight of  6 lb. The horse was born in Barnstead at New Hampshire on April 2010. The current guinness world record for the smallest horse in the world is gold by Thumbelina having a height of  17.5 inches. But the chances for this little guy to break the record of Thumbelina is high. This little horse may soon become the world's smallest horse.

The growth of this little guy is only 35 centimeter and weighs 2.7 kilograms. Einstein is not a dwarf and has no kinds of defects as compared to thumbelina. Its just a little horse, thats all.

But einstein have to wait 2 more couple of years to get a place in guinness book of world records. We can expect that, this little guy to make another record as the world's smallest horse.

Fallstreak Hole

Is it looks amazing?  This picture shows hole punch clouds. These holes are very strange in clouds. The amazing phenomena is called fallstreak holes.

A Fallstreak Hole

Fallstreak hole are rarely occurred and it is a large circular or elliptical gap that can be found in altocumulus clouds. These kinds of holes are usually formed as the temperature of the water present in the clouds is below the freezing temperature. Even after the water is not frozen due to the low level of ice nucleation Particles . When the ice particles do form, it undergoes certain chain reaction which ultimately results in the evaporation of water droplets around the crystal due to the Bergeron process. This phenomena results in the formation of large elliptical or circular hole in the cloud called fallstreak hole.

What about the fallstreak path created by aircraft? Answer is simple.
These ice crystal can be formed by the passing of jet aircrafts which can reduce the pressure behind the wings. As a result air suddenly cools and produce ribbon of ice crystals tailings in the aircraft's path.

The amazing holes have different name such as skypunch, canal cloud, punch hole cloud, cloud hole and hole punched clouds. These kinds of holes in the clouds are rare and very unusual among clouds.
