This card trick will blow your mind…

Andrew Kelly has an awesome trick up his sleeve. Can you figure it out? Source: YouTube
PREPARE to be dazzled.
Magician Andrew Kelly has recently posted a new card trick to his YouTube page and he’s so quick with his hands it’s almost impossible to spot.
Close-up magicians love to wow their audience members by making strange things happen before their eyes and Andrew is no different.
Hailing from the UK, Andrew’s talents have led him to perform in front of some of the world’s top celebrities, including on the Ellen DeGeneres show.
There is no stage, smoke or mirrors in his performances.
He interacts with groups of people at events creating illusions up close with just a pack of cards and borrowed objects such as mobile phones or coins.
This impressive card trick, taught by John Bannon, showcases his skill.
Can you figure out how he does it?

IT has to be seen to be believed.
In the lead-up to the Paris Air Show, which begins on June 15, Boeing has set the bar high after releasing a video of its newest version of the Dreamliner aircraft — the 787-9 — performing some impressive aerial moves.
But it’s the takeoff which has everyone talking as the passenger jet makes an almost vertical ascent seconds after leaving the ground.
The steep climb looks impressive, though it has its doubters.
Boeing 767 pilot Patrick Smith told CNN: “It looks like the takeoff is at a near vertical 90 degree angle — trust me it’s not.”
He said a 787 with passengers making a 20 degree pitch-up on takeoff would be pretty strong.
“Presumably the plane was very light because it wasn’t carrying any passengers, probably had a very light fuel load, no freight, so it would have been able to perform a steeper than normal ascent — but not to the extent the video seems to show,” Smith said.

Disposal of waste plastic is no longer a problem in the steel city with Jamshedpur Utility and Services Company (JUSCO) using bitumen technology on waste plastic, ranging from polybags to biscuit packets, for constructing roads.

JUSCO, a 100 per cent subsidiary company of Tata Steel which maintains and provides municipal services in Tata command area of the city, has constructed 12-15 kms road in the steel city as well as Tata Steel Works besides widening 22 roads using the environment-friendly technology of utilising waste plastic.

As far as we know, Jamshedpur is the only city in eastern India where bitumen technology (Dry Process) patented by Thiagarajar College of Engineering (TCE), Tirupparankuram, Madurai, has been implemented on accumulated waste plastic for the first time”, Gaurav Anand, Senior Manager (Quality Assurance) of JUSCO, said today.
Claiming that there is no maintenance cost involved for the first five years, Anand, who is an environment engineer, said that for every stretch of such one km long and four metre wide road, one tonne of bitumen costing Rs 50,000 is saved.
The use of bitumen has been reduced by 7 per cent ever since JUSCO began using waste plastic in road construction work, he said, adding that the quality and longevity of roads made of waste plastic-aggregate-bitumen was two times better than bitumen road.

Describing plastic tar road as a “new pathway”, Pratyush Dandpat, Deputy Manager (Quality Assurance) of JUSCO, said that the technology turned out to be successful.
Besides being water resistant, it has better binding property, higher softening point, can withstand high temperature and higher load, has lower penetration value, costs less as compared to bitumen road and has no toxic gas emission, Dandpat said.
Though there is great demand for the technology, including from Chattisgarh, Himachal Pradesh, Uttarakhand and Jharkhand governments, but “we do not have any plan to commercialise it but to serve society. We have even received a request from Nigeria, which wants to replicate it in their country”, Anand said.
Due to the JUSCO initiative, the city will now have strong, durable, eco-friendly roads which will also relieve the residents from the sight of heaps of plastic waste.

A Texas A&M University professor and his team in Qatar have a mathematical theory about why search crews have found no trace of Malaysia Airlines Flight 370 more than a year after it went missing.
Dr. Goong Chen, whose research on this theory was published in the American Mathematical Society’s journal, argues that the plane could have nosedived into the Indian Ocean at a 90-degree angle and remained somewhat intact as it sank to the bottom.
At 1:30 a.m. on March 8, the plane carrying 239 people dropped off air-traffic-control screens, less than an hour into a flight from Kuala Lumpur to Beijing.
One of the biggest mysteries surrounding Flight MH370 is the fact that, despite experts tracking the plane’s satellite pings to the southern Indian Ocean, searchers have never found a debris field or oil slicks from the supposed crash.
Texas A&M noted that in the case of Air France Flight 447, crews recovered thousands of pieces of floating debris from the Atlantic Ocean just days after the plane crashed in 2009.
Chen explains that if the plane were to enter the ocean at another angle, it would have created a large “bending moment” from the external force of hitting the water, causing the fuselage to break up.
In this type of situation, there would likely be a field of floating debris on the surface of the water.
But a vertical entry would be much smoother, with a smaller “bending moment.” The plane’s wings would have likely broken off immediately, but since they’re heavy, they probably would have sunk to the bottom of the ocean.
So if the plane nosedived into the ocean, it could have sank somewhat intact and landed belly-up on the ocean floor, according to the research paper.
The ocean’s current would have guided the plane to its resting place at the bottom. Lightweight debris like seat cushions and passenger belongings probably wouldn’t be able to float to the ocean’s surface if the plane’s body sank intact.
The plane stalling from a steep climb, aircraft mechanisms malfunctioning, and the plane running out of fuel could have caused MH370 to plunge into the ocean at a sharp angle, according to the research paper.
Chen and his team created simulations of what the descent might have looked like:

The plane entering the water at this angle wouldn’t have created the same large waves as an entry at a lesser angle. Big waves would have likely caused more break-up of the plane at the surface.
The animation below shows the supposed distribution of pressure. The paper notes that aviation experts say that how a plane enters the water determines how it breaks up.

In other scenarios Chen and his team looked at, the plane’s angle of entry would have created bigger waves and more pressure, which likely would have caused the plane to break up more near the water’s surface.

Chen and his team concluded that based on the various scenarios they mathematically examined, a nosedive is the mostly likely explanation of what happened to the plane. If the plane had entered the ocean at a different angle, the paper notes, search crews would have likely found debris by now.

“This particular assertion is speculative but forensic,” the paper concludes. The team noted that they based this theory on computed data, aviation precedents, and atmospheric and ocean surface conditions.
The disappearance of MH 370 is one of the most bizarre and tragic aviation mysteries of all time. Investigators have not offered any conclusive explanation as to what happened to the plane after it disappeared from radar.
Australian officials announced last month that teams are expanding the MH370 search area in the Indian Ocean. They said that if the plane isn’t found there, they’re not sure where else to look.
