DRY ICE TRANSFORMS DIRECTLY TO FROM BEING A SOLID TO A GAS (WITHOUT TURNING TO LIQUID)

Dry ice, sometimes referred to as "cardice" (chiefly British chemists), is the solid form of carbon dioxide. It is used primarily as a cooling agent. Its advantages include lower temperature than that of water ice and not leaving any residue (other than incidental frost from moisture in the atmosphere). It is useful for preserving frozen foods, ice cream, etc., where mechanical cooling is unavailable.
Dry ice sublimes at −78.5 °C (−109.3 °F) at Earth atmospheric pressures. This extreme cold makes the solid dangerous to handle without protection due to burns caused by freezing (frostbite). While generally not very toxic, the outgassing from it can cause hypercapnia due to buildup in confined locations.
Camphor is also another substance that possesses this sublimation property.

NO FOOD IS NATURALLY BLUE

Blueberries, blue corn, and blue potatoes are actually purple. Blue food is a rare occurrence in nature. There are no leafy blue vegetables, no blue meats, and aside from blueberries and a few blue-purple potatoes from remote spots on the globe, blue just doesn't exist in any significant quantity as a natural food color. Furthermore, our primal nature avoids food that are poisonous. A million years ago, when our earliest ancestors were foraging for food, blue, purple and black were "color warning signs" of potentially lethal food.

THE HARDEST PART OF THE HUMAN BODY IS THE FRONT TEETH (ENAMEL)

The human thigh bones are stronger than concrete, but the hardest part of the human body is the enamel.
The high mineral content of enamel, which makes this tissue the hardest in the human body, also makes it susceptible to a demineralization process which often occurs as dental caries, otherwise known as cavities.

FACTS ABOUT ENGLISH WORDS AND SENTENCES

- "The quick brown fox jumps over the lazy dog" contains all the letters in an alphabet
- All continents in the world start and end with the same letter
- The past tense of "dare" is "durst"
- The word "testify" was derived from a time when men were required to swear on their testicles
- The word "racecar" can be spelt the same way backwards
- "Rhythm" is the longest spelt word without a vowel

YOUR FOOT AND YOUR FOREARM ARE THE SAME LENGTH

THE OPPOSITE SIDES OF A DICE ALWAYS ADD UP TO SEVEN

WHY IS THIS SO?
-Imagine a transparent cube. It has to have an exact centre. From that centre to each given surface which are six, have to be equally balanced. Each opposite sides, which are two, delivers seven dimples in total in order to make the dice purely balanced in order to make it tumble thus making fair game. 
-Opposite sides of a die traditionally add up to seven, implying that the 1, 2 and 3 faces share a vertex. These faces may be placed clockwise or counterclockwise about this vertex. If the 1, 2 and 3 faces run counterclockwise, the die is called "right-handed", and if those faces run clockwise, the die is called "left-handed". Western dice are normally right-handed, and Chinese dice are normally left-handed.

LIGHTNING STRIKES THE EARTH SIX THOUSAND TIMES EVERY MINUTE

Lightning strikes the earth six thousand times every minute and The old saying that 'lightning never strikes the same place twice' is another myth that any veteran storm observer or researcher has seen nature defy. Lightning can strike any location more than once. In fact, given enough time, it is actually inevitable. It may take as little as less than ten minutes within a single thunderstorm, or longer than a million years - but lightning will eventually strike the same spot again and again. A strike to any location does nothing to change the electrical activity in the storm above, which will produce another strike as soon as it 'recharges'. The previously hit location is then just as fair game for the next discharge as any other spot.

YOU CANNOT HOLD YOUR OWN BREATH UNTIL YOU ARE DEAD

This is because of your autonomic nervous system.. you can hold your breath but when you hold it so long that you pass out, your brain will tell your Autonomic Nervous system to make you breath. 

You can't hold your breath forever because after your brain is oxygen deprived for a time you will pass out. When you pass out you will begin to breathe again (assuming there is nothing preventing it) because breathing is an involuntary. That is why when children threaten their mother's with "holding my breath until I die", it's best just to let them try... (Most of them won't make it to the "pass-out" stage anyway.)

A PIECE OF PAPER CANT BE FOLDED MORE THAN SEVEN TIMES

- The number of layers of paper doubles with each fold. So you start with a single layer, then you have two layers, then four, then eight, then 16, then 32, then 64 layers after six folds. Maybe if you are very strong, and you use a pair of pliers, you can get to seven folds and 128 layers, but it probably won’t be pretty.
- At that point the sheet of paper is so small, and the number of layers so large relative to the small size, and the distortion caused by the folds so great, that there is no way to fold it again. You can’t apply enough leverage, and the fibers of the paper do not have enough flexibility for another fold.
- But what if you used a much larger piece of paper, so that you can diminish the effects of fold distortion and paper fiber flexibility? If you use a big enough sheet of paper, you can get to 11 folds, or 2,048 layers, before you reach the limitations of folding.

WINE SPOILS ON EXPOSURE TO LIGHT

Wine is sold in tinted bottles because it spoils on exposure to sunlight. Exposure to heat, light, vibrations or even changes in temperature can spoil wine. Humidity can also dry out a wine cork, causing oxidation and spoiling the wine. Storage of wine is an important consideration for wine that is being kept for long-term aging. While most wine is consumed within 24 hours of purchase, fine wines are often set aside for long-term storage. Wine is one of the few commodities that can improve with age, but it can also rapidly deteriorate if kept in inadequate conditions. The three factors that have the most direct impact on a wine's condition are light, humidity and temperature. A fourth consideration is security for expensive wines. Historically, the storage of wine was handled by wine merchants. Since the mid-20th Century, however, consumers have been increasingly storing their own wine in home-based wine cellars.

HOW TO TEST WHETHER YOUR EGG IS HARDBOILED OR UNCOOKED

1. Lay the egg on its side on a smooth, hard surface
2. Spin it with your fingers and thumb
3. Stop its rotation with a finger tip, by placing your finger directly down on the rotating egg.
4. Lift your finger up immediately

-If the egg remains still, it is hard boiled egg
-If the egg continues to slowly rotate, it is uncooked

FOODS CANT BE TASTED WITHOUT SALIVA

The tongue is a muscle with glands, sensory cells, and fatty tissue that helps to moisten food with saliva. You cannot taste food unless it is mixed with saliva. For instance, if salt is placed on a dry tongue, the taste buds will not be able to identify it. As soon as saliva is added, the salt dissolves and the taste sensation takes place.

See: You cannot taste food unless it is mixed with saliva

Try the Experiment
Materials
*.dry food, such as cookies, crackers or pretzels
*.paper towels
*.water
Experiment
1.Dry your tongue! Lint-free paper towels are a good choice, but if you'd rather use your shirt or arm or whatever, I'm not going to stop you.
2.Place a sample of dry food on your tongue. You'll get the best results if you have multiple foods available and you close your eyes and have a friend feed you the food. This is because some of what you taste is psychological. It's like when you pick up a can expecting cola and it's tea... the taste is "off" because you already have an expectation. Try to avoid bias in your results by removing visual cues.
3.What did you taste? Did you taste anything? Take a sip of water and try again, letting all that saliva-goodness work its magic.
4.Lather, rinse, repeat with other types of food.

7 SEVEN NEW WONDERS OF THE WORLD

 

Christ Redeemer: Rio de Janeiro, Brazil

This statue of Jesus stands some 38 meters tall, atop the Corcovado mountain overlooking Rio de Janeiro. Designed by Brazilian Heitor da Silva Costa and created by French sculptor Paul Landowski, it is one of the world’s best-known monuments. The statue took five years to construct and was inaugurated on October 12, 1931. It has become a symbol of the city and of the warmth of the Brazilian people, who receive visitors with open arms.

 

Great Wall of China: China

The Great Wall of China was built to link existing fortifications into a united defense system and better keep invading Mongol tribes out of China. It is the largest man-made monument ever to have been built and it is disputed that it is the only one visible from space. Many thousands of people must have given their lives to build this colossal construction.

 

Machu Picchu: Peru

In the 15th century, the Incan Emperor Pachacútec built a city in the clouds on the mountain known as Machu Picchu (“old mountain”). This extraordinary settlement lies halfway up the Andes Plateau, deep in the Amazon jungle and above the Urubamba River. It was probably abandoned by the Incas because of a smallpox outbreak and, after the Spanish defeated the Incan Empire, the city remained ‘lost’ for over three centuries. It was rediscovered by Hiram Bingham in 1911.

 

Petra: Jordan

On the edge of the Arabian Desert, Petra was the glittering capital of the Nabataean empire of King Aretas IV (9 B.C. to 40 A.D.). Masters of water technology, the Nabataeans provided their city with great tunnel constructions and water chambers. A theater, modelled on Greek-Roman prototypes, had space for an audience of 4,000. Today, the Palace Tombs of Petra, with the 42-meter-high Hellenistic temple facade on the El-Deir Monastery, are impressive examples of Middle Eastern culture.

 

Pyramid at Chichén Itzá: Yucatan Peninsula, Mexico

Chichén Itzá, the most famous Mayan temple city, served as the political and economic center of the Mayan civilization. Its various structures – the pyramid of Kukulkan, the Temple of Chac Mool, the Hall of the Thousand Pillars, and the Playing Field of the Prisoners – can still be seen today and are demonstrative of an extraordinary commitment to architectural space and composition. The pyramid itself was the last, and arguably the greatest, of all Mayan temples.

 

Roman Colosseum: Rome, Italy

This great amphitheater in the centre of Rome was built to give favors to successful legionnaires and to celebrate the glory of the Roman Empire. Its design concept still stands to this very day, and virtually every modern sports stadium some 2,000 years later still bears the irresistible imprint of the Colosseum’s original design. Today, through films and history books, we are even more aware of the cruel fights and games that took place in this arena, all for the joy of the spectators.

 

Taj Mahal: Agra, India

This immense mausoleum was built on the orders of Shah Jahan, the fifth Muslim Mogul emperor, to honor the memory of his beloved late wife. Built out of white marble and standing in formally laid-out walled gardens, the Taj Mahal is regarded as the most perfect jewel of Muslim art in India. The emperor was consequently jailed and, it is said, could then only see the Taj Mahal out of his small cell window.

BEST TEAMS IN THE CHAMPIONS LEAGUE (2014)

10. Borussia Dortmund – 83.311 ranking points
The 10th highest ranked team in the Champions League is Borussia Dortmund, who reached the final in 2013. The Germans have emerged as a real European force over the past couple of years and are once again considered contenders for club football’s biggest prize – a tournament they won in 1997. Their dismal showing just prior to the Klopp-inspired resurrection counts against them in their coefficient points however, explaining their seemingly low ranking.
9. FC Porto – 89.009 points –
The two-time winners of the European Cup, Porto have been one of the regular features in the competition. The Portuguese giants have seen mixed fortunes over the last four campaigns, but their pedigree ensures they are in the top 10.
8. Arsenal – 91.992 points
Drawn among the top seeds in this season’s iteration of the tournament, Arsenal are at real risk of slipping from the leading pack ahead of next year’s competition (should they qualify that is). Despite being a regular fixture in the Champions League, the Gunners failure to get beyond the last-16 in recent seasons is starting to hinder their coefficient ranking.
7. Schalke 04 – 96.311 points
While they were in pot two for this season’s draw, if everything was remain as it is right now, Schalke would be among the big guns of pot one. The German’s semi-final appearance in 2011 adds huge weight to their ranking and as such they are technically the seventh best team in the tournament right now.
6. Atletico Madrid – 99.599 points
Last season’s runners up, Atletico Madrid have been inconsistent in Europe to say the least. However, a huge 37.600 points for reaching the final last season, paired with their 34.171 points for winning the Europa League in 2012 means the La Liga giants are well within the top ranked teams in the competition.
5. Benfica – 113.009 points
Consistency has been the keyfor Benfica, with the Portuguese outfit having reached two Europa League finals and a Champions League quarter final in the last three years. That impressive return has benefitted them in terms of UEFA ranking.
4. Chelsea – 122.992 points
It is unsurprising to see Chelsea this far up the rankings, especially given their success in Europe in recent years. A Champions League final victory followed by glory in the Europa League 12 months later certainly boosted their coefficient points total.
3. Bayern Munich – 128.311 points
Unquestionably one of the giants of world football, Bayern Munich’s consistent positioning in the semis and finals has seen them close the gap on the continent’s leading sides. Expect to see their ranking increase further come next season.
2. Barcelona – 131.599 points
The four time winners of the European Cup, Barcelona’s place among the elite of the world football is never in doubt. Their continued success and strong finishes over the past four seasons means they are the second highest ranked team.
1. Real Madrid – 143.599 points
At number one with a huge 12 point advantage is Real Madrid. Los Blancos have crashed out at the semi final stage three times over the last four years, and crucially won the competition – the famed La Decima – last year to put them head and shoulders above everyone else. The only way they will not remain top of the rankings would be if they failed to escape the group stages this year.
