Staff at an aquarium in Blackpool say they were shocked to discover there was a unknown shark swimming around their tank.

Bosses at the Sea Life centre only realised the presence of the mystery shark when they spotted two shark eggs in the massive half-a-million litre tank.

Because the sharks known to be in the tank only give birth to live young, they concluded there was another hidden one somewhere in there.

Experts think the still undiscovered shark is an easily camouflaged tropical carpet shark which may have been introduced by one of several former aquarium curators.

A spokesperson for Sea Life Blackpool said: "When we found the first egg during a routine dive in the ocean tank just before Easter, we initially thought it must be artificial, and part of the tank's theming decor.

"We were all completely baffled when we took a closer look and realised it was real, and then we found another one about three weeks later."

"A small carpet shark would possibly feel threatened by the larger sharks in the tank, which is the only explanation we can come up with for it keeping out of sight for so long.

"Ideally, we would like to move her to a smaller tropical tank and provide her with a mate."

Ivan Stoiljkovic (born 2005) is a Croatian boy who is purportedly able to "magnetically" attract metal objects to his body. Stoiljkovic, who lives in the city of Koprivnica, also could rollerblade at the age of 15 months, having learnt to walk at the age of 8 months. He learnt how to ride a small motorcycle at the age of two. His family also claim that he has magical healing powers, which he used to cure a stomach wound incurred by his grandfather.

In many respects, Ivan Stoiljkovic is much like any other six-year-old boy in his city.

He enjoys kicking a ball around in the garden of the home he shares with his family and is learning to play the accordion as a hobby.

But there are some areas of his magnetic personality where Ivan differs greatly - namely his ability to stick metal objects to his body.

There are also claims from his family in Koprivnica, in Northern Croatia, of unusual levels of strength and even healing powers.

But one thing is for certain - when Ivan takes off his shirt, he is able to stick metallic objects such as spoons, mobile phones and even frying pans to his body.

In total, his family says, he can carry up to 25kg of metal stuck to his torso.

In the video below, his grandmother Dragica adds metal objects of various sizes to his torso, including a huge metal frying pan.

'I have no problem to hold metal objects, but eventually I get tired,' said Ivan.

But that isn't the end to Ivan's unusual talents.

According to his family, Ivan has also used his 'healing' hands to alleviate stomach pains for his grandfather Ivo and is credited with soothing the pain of a neighbour who hurt his leg in a tractor accident.

Ivan said that when his grandson laid his hands on his stomach, they became extremely hot and the pain simply went away.

'When something hurts us, we ask Ivan to put his hands on the sore and the pain disappears in a flash,' said Dragica.

If that wasn't enough, it is also claimed Ivan is much stronger than other children his age and is able to easily carry bags of cement as heavy as 50lb.

His abilities echo the character Magneto, as featured in the X-Men comics and films, a mutant who has the ability to manipulate metals.

Magneto was played by Sir Ian McKellen in the X-men trilogy of films, and will be played by Michael Fassbender in the upcoming prequel X-Men: First Class.

Taiwanese hairdresser Tsai Shiou-ying has won many prizes for her cutting and decorative hair extensions in a four-decade career.

Now she has gone one step further, making decorations including shoes, brooches, fruit and animals from hair left on the salon floor after the cutting is done.

Tsai, who started working with hair in her teens and learned the skills of styling from her mother, recently showed off some of her creations in her small salon in the central city of Taichung.

Her pride and joy is a pair of high heels made entirely from human hair that for her are a substitute for the real thing.

"I personally love high heels very much, but I am flat-footed. I can only look at them and try them on, but if I buy them they will only be stored away until mold grows," the 54-year-old said.

"I can't wear them, so I want to make a pair of heels that I really like. This way, even if I can't wear them, at least I created a work of art."

Only real hair can endure the shaping process, Tsai explains. A single heel needs hair from at least three people, and she asks her neighbours and relatives to contribute to her stock. It takes a month to make a single pair of hairy heels.

"With real hair, I can perm and dye it into all sorts of different colors," she said.

"Also, in the process of making, if I need to shape the hair I would apply instant glue or super glue -- they damage plastic hair, but won't damage real hair."

To develop her hobby further, Tsai is now planning a range of hairy corsets and dresses. But her works, which also include elaborate flower-shaped brooches in purples and greens, a life-size pineapple and a black rat with bright blue eyes, are not for sale.

Asked if she was worried that some people might think her hobby is in rather bad taste, Tsai said there was nothing to fear from hair.

"All the hair was cut off on-site, and even if it was given by my friends, it would be just cut off from someone, so this won't have anything to do with taboos about dead people's hair. Some people watch too many horror movies, so they imagine paranormal events and become afraid."

Popsicles are normally a effective and cheap way to cool off -- but not at a hotel resort in Mexico, they've launched a lavish $1,000 tequila ice lolly.

The expensive icy treat may come served on a classic plastic stick, but it's made from premium tequila which sells for £1,000 per bottle rather than fruit squash.

But should the Tequilas Premium Clase Azul Ultra not be enough of a draw, there is also the little matter of the 24 ct. gold flakes the Tequila Pop contains.

Bosses at the Marquis Los Cabos resort in Baja California Sur say they expect the premium popsicle to prove popular, but that those on a budget may prefer a straight shot of the Clase Azul Ultra… a snip at $500 a shot.

Airline food served on little plastic trays is always sure to divide opinion -- but one unique restaurant is redefining what you'd expect to eat on-board a plane.

That's because this unusual eatery, which is the first of it's kind in the UK, is set inside a Douglas DC6 aircraft and run by 35-year-old chef Tony Caunce at Coventry Airport.

With a fully-functioning bar on-board, punters can enjoy draught beers and wines with food from under a tenner up to just £15 for a fillet steak...meaning the owners can brag that the prices aren't too sky high.

The 40-seater restaurant opened two weeks ago with an aviation-themed menu including an 8oz Rapide, Vampire gammon steak, Bomber T-bone steak and a Meteor marinade fillet… luckily you don't have to eat with a tiny plastic knife and fork.

Punters can also have a look at the original cockpit to see what the plane was like when it was flying. Waiters can be called to tables using the original call buttons as you would find on a flight to call a stewardess.

"The plane is an old DC6," said owner Mr Caunce. "It was in use all around the world until only about three and a half years ago.

"It used to fly all across the world, lots of flights to Spain but also transatlantic flights.

"It's a good space for a restaurant and attracts people who are interested in planes as well as people coming through the airfield.

"We've only been open for two weeks but we've already catered for large parties of people coming through the airfield."

Retired pilot Eamonn Williams, who used to fly the plane in it's heyday says he believes the idea is excellent: "I'm ecstatic to see it in use like this, I went as soon as it opened, I loved it, it's a fantastic place to be and they do great food," said 52-year-old Mike.

"The DC6 is my favourite of all the planes I ever flew," said Mike, who retired from flying four years ago and lives in Coventry.

"I flew jumbo jets at the end of my career, which was a sort of childhood dream, but it had nothing on the DC6."

The plane, which is over 50-years-old, was built to fly 92 passengers in comfort across the Atlantic, before being converted to carry cargo, which included transporting race horses.

Yesterday, Canadian company Dairy Queen has set a new world record by making the world’s largest ice-cream cake in Yonge and Dundas Square, Toronto.

It took 100 people over a year to plan the event, but after 30 years and 52 million ice-cream cakes sold, this was the perfect way to celebrate, according to Denise Hutton, vice-president of marketing at Dairy Queen Canada. Dozens of chefs worked around the clock using over 9,000 kg of ice-cream, 91 kg of sponge cake, around 136 kg of icing and Oreo crumbles, to beat the former world record, a nearly 8,000 kg ice-cream cake made by China, in 2006.

After the cake was completed and acknowledged by the Guinness Book of Records, pieces of it were served to the crowd gathered in Yonge and Dundas Square, with 100% of suggested donations going to Children’s Miracle Network. “When else can eating ice cream cake help to fund medical care, research and educational programs so that Canadian kids have access to world-class care? It’s the best of all worlds – a delicious treat and a great cause.” said the charity’s Paul Lethbridge.

Chefchaouen or Chaouen is a city in northwest Morocco. It is the chief town of the province of the same name, and is noted for its buildings in shades of blue.

One of Morocco’s most popular tourist destinations, Chefchaouen is most known for its blue-rinsed buildings, hotels and alleys, an old tradition leftover from the city’s Jewish population.

Chefchaouen was founded by Moorish exiles from Spain, in 1471, as a small fortress to fend off the attacks of invading Portuguese forcess in northern Morocco. After the Spanish Reconquista, the small mountain town became one of the largest Moriscos and Jews refuge sites, and during their stay they managed to leave their mark on it, one that makes the modern city so special.

The name Chefchaouen comes from “chauen”, which is Spanish for horns, and refers to the shape of the two mountains overlooking the settlement. But it’s not its strange name, the beautiful and unique handicrafts sold by local craftsman, or the delicious goat cheese that attracts the majority of tourists to Chefchaouen. It’s the blue-painted houses and buildings of the city, a tradition inherited from the former Jewish inhabitants. In the Bible, Israelites are commanded to dye one of the threads in their tallit (prayer shawl) blue, with tekhelel. This was an old natural dye, processed from a species of shellfish, but in time its production collapsed and the Jewish people eventually forgot how to make it. But, in honor of the sacred commandment, the color blue was still woven into the cloth of their tallit. When they look at the dye, they will think of the blue sky, and the God above them in Heaven.

While the Jewish population of Chefchoauen isn’t as numerous as it one was, practically everyone in the city still follows this old tradition and frequently renew the paint job on their homes.

A Cuban cigar roller has begun rolling a 70-metre cigar in an attempt to nearly double his previous Guinness world record, a spokesman said.

Working eight hours a day for nine days, 67-year-old Jose 'Cueto' Castelar is hoping to break his 2009 record of a 43.38m long stogie.

He hopes to complete his latest feat on May 3 and display it at the International Tourism Fair, which runs from Monday to Saturday next week. It would be his fifth record in more than half a century of cigar-rolling.

"Cueto said that as long as he lives, the Guinness record has to be in Cuba," said his spokesman Amado de la Rosa. "He is very lively now and will get tired as the days go by, but he hopes to reach his goal."

Mr Castelar first learned to make cigars when he was 14 years old.

Handmade Cuban cigars are considered to be the finest in the world.

Tobacco is one of the communist island's top exports, along with nickel, biotech products, sugar, coffee and fruit.

Outside this improbable spa in a remote part of the former Soviet Union, oil rigs bob on a hardscrabble plain of rocks, shrubs and rusting industrial equipment that could easily pass for a stretch of West Texas.

Inside, Ramil Mutukhov, a lanky 25-year-old, prepares to be pampered and preened, scrubbed and peeled — in a bath of pure crude oil.

He undresses, hangs his trousers and sweatshirt on a peg, pulls off socks and underwear and folds a wad of brown paper towels. He will need them later. Then he steps into a mess of what looks, smells and flows like used engine oil. “It’s wonderful,” he says, up to his neck in oil in a sort of human lube job.

The petroleum spas of Naftalan in central Azerbaijan, one of the little-known but once popular vacation spots of the Soviet Union, are making an unlikely return in a country so awash in oil these days that people are swimming in it.

Here in Naftalan, visitors can bathe once a day in the local crude. They and doctors here say it relieves joint pain, cures psoriasis, calms nerves and beautifies skin — never mind that Western experts say it may cause cancer.

Hoping to tap into the worldwide spa boom, Health Center, where Mr. Mutukhov took a dip recently, opened a year ago. Another spa is being built and two more are planned. “Two years ago, all this was ruins,” Ilgar Guseynov, the owner and director of Health Center, said in an interview. “Every day, every month, Azerbaijan is growing richer.”

At their peak in the 1980s, Naftalan spas had 75,000 visitors a year. That flow became a trickle after war broke out between Azerbaijan and ethnic Armenians in nearby Nagorno-Karabakh in 1988 — and after the Soviet Union stopped offering free trips. Five of the six Soviet-era resorts were converted into glum housing for refugees. But this summer, about 350 people visited the Health Center, Mr. Guseynov said, up from 250 last summer. A 15-day course costs $450, including meals.

“Azerbaijan is standing on its own feet now,” Amir Aslan, the deputy mayor of Naftalan, said. The town is banking on growth tied to the oil spa, which he said would pull it out of poverty. He has plans for a $3 million, 20-bath spread and is seeking investors.

In her office overlooking the oil field that supplies Health Center, Gyultikin Suleymanova, the lead doctor, said the local crude was unusual because it contained little natural gas or other lighter fractions of petroleum, and as a result was safe.

Naftalan crude contains about 50 percent naphthalene, a hydrocarbon best known as the stuff of mothballs. It is also an active ingredient in coal tar soaps, which are used by dermatologists to treat psoriasis, though in lower concentrations.

The National Agency for Research on Cancer, an American government agency, classifies naphthalene as a possible carcinogen, though Dr. Suleymanova said that is not the case when people bathe in it. Baths are lukewarm and last 10 minutes.

The therapeutic benefits are a product of natural antibiotic and anti-inflammatory agents that seep into the skin, she said. Arzu Mirzeyev is the bath master. With a green frock, jeans stained with oil and a mustache, he looks for all the world like a gas station mechanic and has a job to match. He changes the oil.

Each bath uses about a barrel of crude, which is recycled into a communal tank for future bathers, given the cost of oil these days. Mr. Mirzeyev also uses paper towels to wipe bathers clean, a long, hard process that involves several showers.

He says he likes his job. Until Azerbaijan’s economy ticked up in the last two years, Mr. Mirzeyev, 40 and a father of three, was a seasonal laborer in Ukraine, where wages were higher.

“If we have visitors, then we have work,” he said.

Unlike the oil from Azerbaijan’s offshore deposits, sold internationally under the brand Azeri Light crude, Naftalan’s oil is too heavy to have much commercial value. Luckily, because most of the bath attendants and patients seemed to smoke, it is not particularly flammable, either.

The resort has 80 rooms and 10 tubs, 5 for women, 5 for men. The tubs are not scoured between baths and, as might be expected, have perhaps the world’s worst bathtub rings — greasy and greenish brown.

Oil has been Azerbaijan’s ticket for a long time.

Oil seepages have been noted in Naftalan since at least the 13th century, when Marco Polo passed through and, even today, a reedy marsh, about the size of a football field, has a black patina of oil on the water. The site was a stopping place on the Silk Road to China.

Later, Azerbaijan’s larger oil reserves on the Caspian coast were developed by the Swedish Nobel brothers, the rivals of the American oil tycoon John D. Rockefeller.

In a sign of the more recent past in Naftalan, a museum keeps a collection of wooden crutches left by Soviet-era visitors “cured” by oil at the peak of the Soviet oil spa boom in the 1970s and 1980s.

The museum also has a photograph of a sign that hung at the city limits back then, “He Who Has Naftalan Has Everything.”
