Levitating humans could be in our future, thanks to a scientific breakthrough in acoustic tractor beam technology, which can now lift larger objects than ever before.
Engineers from the University of Bristol have demonstrated that it’s possible to stably levitate objects using the world’s most powerful acoustic tractor beams. Their findings were published in the Physical Review Letters on Monday.
Acoustic tractor beams use soundwaves to hold particles in the air. It was previously believed they could only be used to levitate very small objects which were about the same size as a wavelength of sound, but the research demonstrates the potential for far larger objects to be levitated.
“Acoustic researchers had been frustrated by the size limit for years, so its satisfying to find a way to overcome it,”said the study’s lead author, Dr Asier Marzo of Bristol’s Department of Mechanical Engineering. “I think it opens the door to many new applications.”
The technique creates a tornado-like effect with acoustic vortices, which researchers said are like, "tornadoes of sound, made of a twister-like structure with loud sound surrounding a silent core."
If you honestly believed that your job was hard to do, take a gander at this video showing scuba divers working to dig an underwater trance using numerous forms of equipment including specially built excavators.
Watch how quickly the seemingly clear water turns into a mixture of water and dirt, instantly making what seems to be a somewhat difficult job that much harder.
An astronaut has blown away people on social media after he was filmed 'flying' on a vacuum cleaner while aboard the International Space Station .
The Russian cosmonaut Anton Shkaplerov, 45, stretched out his arm like Superman for the unusual slow-motion flight - to the famous R Kelly tune.
Shkaplerov was the commander of the Soyuz MS-07 spaceflight last month which took him and two other astronauts, Scott Tingle from the US and Japan's Norishige Kanai, to the ISS.
He is serving the space station's Expedition 54 as a flight engineer and he will be the commander of Expedition 55.
Marine Light Attack Helicopter Squadron 367 got three redesigned AH-1Z Viper assault helicopters at Marine Corps Base Hawai, December 19, 2017.
The AH-1Z airplane is a refreshed variant of the AH-1W, bringing new abilities and highlights into the squadron's arms stockpile.
"The AH-1Z's are supplanting the AH-1W's, which are basically from the 1980's," said Marine Corps Captain Julian Tucker, the squadron's ground preparing officer. "Some huge takeaways on the new airship can be abridged into more noteworthy fuel limit, weapons abilities, and situational mindfulness".

This is the moment a pot of boiling water is flung into the air only to immediately freeze over head.
The footage shows a man in the town of Couburg, Ontario, Canada, braves temperatures of -34C to attempt the stunt.
As he flings the pot skywards the scolding water freezes in an instant resulting in a deluge of ice.
Similar videos have been uploaded online before with the astonishing outcome believed to be the result of Mpemba effect, the observation that in certain circumstances warmer water freezes faster than cold.
