What does the name Scotch whiskey mean?

Most of us know that scotch whiskey is from Scotland but it's not all. The name of this kind od wine includes some other amazing news that will make you surprise.

Scotland

The title of “Scotch” is defined and regulated by a document created on November 23, 2009 called the “Scotch Whisky Regulations 2009” or SWR. Not only regulating production, the act also governs the labeling, packaging and the advertising of Scotch whisky within the United Kingdom. The SWR is a complete replacement of the previous regulations which focused exclusively on the production process. While the SWR is technically only valid within its jurisdiction, international trade agreements have been put in place which effectively make some provisions of the SWR apply in countries outside the United Kingdom.

The document defines Scotch whisky in the following manner:

1. Must be produced at a distillery in Scotland from water and malted barley (to which only whole grains of other cereals may be added) all of which have been:
  •  Processed at that distillery into a mash
  • Converted at that distillery to a fermentable substrate only by endogenous enzyme systems
  • Fermented at that distillery only by adding yeast
  • Distilled at an alcoholic strength by volume of less than 94.8% (190 US proof)
  • Wholly matured in an excise warehouse in Scotland in oak casks of a capacity not exceeding 700 litres (185 US gal; 154 imp gal) for at least three years

2. Scotch whisky must retain the color, aroma and taste of the raw materials used in, and the method of, its production and maturation.

3. It may not contain any added substances, aside from water and plain (E150A) caramel coloring.

4. It must comprise a minimum alcoholic strength by volume of 40% (80 US proof).

Interesting information about tigers

Reading for more interesting information about tigers facts

1. Tigers Hunt By Ambush


A tiger prefers to attack by surprise, if the tiger knows he or she has been spotted it is very unlikely it will attack. In some places in India the locals wear masks with a head facing behind to prevent tiger attacks.

2. Tigers cannot purr.

You might think that because it’s simply a big cat a tiger would be able to purr, right? Well, that’s actually not the case. Instead of purring to show happiness, a tiger will actually squint its eyes or even close them completely. Since losing vision lowers the tigers defenses, it will only do this if it feels very comfortable and safe. Closing its eyes around you translates to “I feel very happy when you’re here, so much so that I can relax for a bit!”

3. Tigers have been known to imitate the call of other animals to successfully attract prey.

Bears and tigers will typically cross paths with each other since their habitats can overlap. It would make sense, then, that tigers have developed a taste for bears and bear food. In order to lure a bear directly, tigers have been known to imitate the sound of a bear’s prey. Once the bear is close enough (thinking its found a meal for itself) the tiger attacks.

4. Most tigers have yellow eyes, but white tigers usually have blue eyes

The gene for blue eyes is usually linked to the gene for white fur, so white tigers are much more likely to have blue eyes, rather than the typical yellow kind. In addition to the blue-eyed gene being linked, the gene for being cross-eyed, or boss-eyed, is also linked, so many white tigers have crossed blue eyes. Darn! Gorgeous blue eyes have to come with a price, I guess.

5. Tigers have spiked penises

Ouch. Just writing that sentence made me uncomfortable! Tigers are unable to become erect when aroused. Instead, males penises’ have a bone located inside (called a baculum) and are covered with barbs. Those prickly spikes aid in “keeping the connection” (no pun intended) between the male and female during copulation.

6. A backhand from a tiger can kill you

While tigers typically prefer to use their 10 cm long teeth to crush a victim’s jugular (lovely!), a single strike is enough to do some serious damage. One swipe from a tiger’s front paw is strong enough to smash a bear’s skull or even break its back. Tiger, please. 

7. Tigers can come in a variety of colors

Photo Credit: Tambako the Jaguar

Different hair color genes can cause a tiger to vary from its usual black and orange coloration. A tiger’s coat can be white, gold, black, and quite possibly even blue. While there have been reports of blue tigers, called Maltese Tigers, there have been no verified specimens with this unique coloration… though I have seen enough photoshopped pics to start believing there might have been.

7. A Tiger’s Stripes Are Also On Their Skin


If you shaved all the fur off a tiger you will still be able to see it’s stripes on the cat’s skin.

From head to tail, males can measure from two to three meters. The height of his withers (neck) is of 91 cm. The males weights about 250 kg. He can live up to 25 years. He lives in the south of the Sundarbans delta, the largest mangrove forest in the world, which lies in India, and spreads across areas of Bangladesh.

Bengal tigers can also be found in north and central India, as well as in Birmania and in Nepal.

In 1900, they were about 40.000 – 50.000. Around 1972, there remained 1.850. In 1984, thanks to a program of protection, they were numbered approximately 4.000.

Tigers hunt at night. They assault their preys on the side or at the back. They bit to death at the nape of the neck small preys; they bit at the throat bigger preys and let them suffocate to death. The Bengal tiger hunts the “yaur” (kind of wild bull), the buffalo, the (wild) boar, monkeys and lizards. When hungry, a tiger can kill up to 30 buffaloes per annum. He can also eat 31 kg of meat within a night. It takes between 2 or 3 days for a tiger to eat its prey. Between two meals, he covers its prey with leaves.

The Bengal tiger usually breeds in the springtime. A male from a neighbouring field comes on the female's field. About 15 weeks later, the tigress brings between 2 and “babies” into the world, sightless during the first ten weeks. After eight weeks, the latter will be able to start eating the little preys brought by their mother. The tiger is a night hunter and lonesome. He does not like sharing his territory with other tigers. Tigers mark their territory by urinating and secreting which smell strongly and indicate their presence. They can also savage to pieces the bark of a tree. He can run up to 45 km per hour.

A tiger print can measure 13 cm of diameter that is to say the equivalent to your two hands placed side by side. A forefoot has five fingers, and a hind foot has four fingers. Thanks to the cushions under his feet, the tiger can approach a prey without making any noise and absorb the choc of his gigantic leaps.

During the warm hours of the day, the tiger stays in one of his cool hiding places. His strong smell is so dread that not one single animal dares to disturb him while he's resting. He tiger has a fur striped with black, white and reddish-brown. He becomes invisible when he hides away in the long grass of the jungle. Thanks to his camouflage, he can approach his preys without been noticed. A tiger inspects is territory everyday. It takes him three days to go round and visit all his hiding-places. Intruders: beware! The anger of the master of this place can be violent!

Magellanic Penguin

Penguin Habitat
Most penguins spend about ¾ of their time in the water. Their bodies are designed to easily adapt to the water.

Penguin Distribution
It is a common misconception that all penguins live in icy climates. While many of them do it isn’t something that is necessary in order for them to survive.

Penguin Feeding
The primary sources of food for penguins include krill, small fish, and crustaceans. Many species of penguins prefer to hunt near the shoreline.

Penguin Reproduction
There are some great qualities of penguins found in their reproduction process. They can mature for reproduction from about 4 to 8 years of age.

Penguin Anatomy
The overall anatomy of a penguin is very complex as well as interesting. Their bodies are designed to allow them to survive in their natural habitat.

Penguin Communication
Penguins are very effective communicators, especially with their mates. This is due to the fact that they have to work together in order to care for the eggs and for the offspring.

Penguin Evolution
It is believed that the penguins are derived from a type of bird that is able to fly. Yet they needed to be able to adapt to the waters if they were going to be able to survive.

Penguin Predators
There are quite a few types of predators out there that find penguins to make the perfect meal.

Penguin Social Structure
It is believed that it is their social status that allows them to be able to interact and to survive the harsh winters in many areas.

Facts that you didn't know about elephant facts of eating habits

What do African and Asian elephants eat?


The African elephant is much larger that the Asian elephant and consequently eats a lot more than the latter. While an average African elephant will need 250 kilograms of food and drink 60 liters of water the Asian elephant will eat 150 kilograms and drink 40 liters of water. Both species will feed mostly in the early morning and in the late evenings.

The African elephant is found in all types of habitats ranging from the savannahs to marshes and deserts and even in mountains above the snow line. Because of the terrain they live in and because of their higher reach they are browsers. They eat leaves, soft shoots, woody plants, shrubs and fruits of high growing trees. They will often rip bark off trees. They will often uproot trees, a habit which can change savannah into grasslands.

The Asian elephant lives in the thorn-scrub forests of Sri Lanka, Southern India and Thailand and in the evergreen forests and are grazers. They will generally feed on grasses, low woody plants and trees. As bamboo is abundant in these regions the Asian elephant is very fond of them.

How much do elephants eat?


An interesting fact is that elephants do not have a very efficient digestive system and they digest, on an average, only forty percent of the food they eat. That makes the quantity of food they require even larger. A large male African elephant may eat as much as 350 kilograms of vegetation in a day. They also have to drink a lot of water. Elephants may spend as much as 18 hours a day foraging for food and water. Because they consume such quantities, elephants live close to water as the live to the food source. They are also very good swimmers so they often swim in search of food from one place to another.
 For more facts tigers facts
Elephants have 26 teeth. Unlike most other mammals that first develop baby teeth that are later replaced by a set of permanent teeth elephants have cycles of tooth replacement throughout their lives and may be typically replaced six times in a lifespan. This helps them eat the tough tree barks and the roots till late into their lives. An elephant with an infected tooth cannot survive for long in the wild because it cannot eat properly, and tooth replacements help.

What make tiger becomes India's national animal?

Learn all information you wanted about tiger facts by this article:

The Tiger (Panthera Tigris,Linnaeus) is the national animal of India. Tiger is also called the lord of Jungles. The national animal of India, is rich-colored well-striped animal with a short coat. As the national animal of India, tiger symbolizes India's wildlife wealth. The combination of grace,strength, agility and enormous power has earned the tiger great respect and high esteem.


Out of the eight races of the species known, the Indian race, the Royal Bengal Tiger is found throughout the country (except the north-western region) and also in the neighboring countries like Nepal, Bhutan and Bangladesh. Tigers are now getting extinct. The Government of India, under its "Project Tiger" program, started a massive effort to preserve the tiger population in 1973. Today, the tiger advances as a symbol of India's conservation of itself and its wildlife heritage. Since the launch of "Project Tiger", the tiger population has shown a gradual increase. So far, 23 tiger reserves have been established in the country under this project.

The tiger was adopted as the National Animal by the Indian Board for Wildlife in 1972 in place of the lion. It was selected as a national animal because of its presence in larger parts of the country. It is found in 16 states while the lion is found only in one state. Also, because of the worldwide importance of the animal, and the need to protect it. Tiger as the National Animal of India symbolizes the power, strength, elegance, alertness, intelligence and endurance of the nation. Tiger has also been long part of Indian mythology and folklore.

How is a rainbow formed?


Most of us like to see rainbow, but how many of us know the science facts that how is a rainbow formed? See the writing to know more:



One of nature's most splendid masterpieces is the rainbow. A rainbow is an excellent demonstration of the dispersion of light and one more piece of evidence that visible light is composed of a spectrum of wavelengths, each associated with a distinct color. To view a rainbow, your back must be to the sun as you look at an approximately 40 degree angle above the ground into a region of the atmosphere with suspended droplets of water or even a light mist. Each individual droplet of water acts as a tiny prism that both disperses the light and reflects it back to your eye. As you sight into the sky, wavelengths of light associated with a specific color arrive at your eye from the collection of droplets. The net effect of the vast array of droplets is that a circular arc of ROYGBIV is seen across the sky. But just exactly how do the droplets of water disperse and reflect the light? And why does the pattern always appear as ROYGBIV from top to bottom? These are the questions that we will seek to understand on this page of The Physics Classroom Tutorial. To understand these questions, we will need to draw upon our understanding of refraction, internal reflection and dispersion.




The birth of each rainbow begins with millions of tiny rain droplets. The rain droplets serve as a type of reflector of light. White light enters one individual rain droplet and exits as one specific color of the spectrum. Without millions of rain droplets, a rainbow would not occur. If you only had a few rain droplets you would only see a few colors. This is typically why rainbow appear after a rain storm.
Each rain droplet has a function in the formation of the rainbow. Sunlight enters the rain droplet at a specific angle and the rain droplet separates the white light into many different colors.

This angle is a fixed measurement between your eye and the sun. What color is refracted depends upon the critical angle, which is the angle the sunlight strikes the back of the rain droplet. Red light bends the least, exiting the rain droplet at a 42 degree angle, while Violet light bends the most, exiting the rain droplet at a 40 degree angle. All of the other colors of the rainbow exit the rain droplets at some angle between 40 and 42 degrees, thus making up the colors of the rainbow ROYGBIV, this order never changes.
Each rain droplet reflects all colors at a given point and time, but only one color comes back to your eye, requiring million of rain droplets to create a rainbow. As the rain droplets fall through the sky, the colors of the spectrum being reflected and refracted are constantly changing.
