Scientists have demonstrated small boats that float upside down below the levitation level of a liquid with the astonishing agility of physics.
Researchers in Paris were also investigating the effect of vert tremors, which could be used to deflect fluid levels in mid-air.
The liquid level on the suspended mattress was only able to float, but the small model boat floated on the bottom surface due to the intense air pressure.
This counter-intuitive behavior is the result of constant vibrations, which change the forces acting on a floating object object.
In this case of ‘reverse-buoyancy’ there may be practical use in transporting the material by liquid and separating the contaminants from the water.
The footage shows an experiment in gravity-observing physics, inspired by fantastic surrealistic art, science fiction and Pirates of the Caribbean.

An example of a reverse boom is a plastic boat floating below and below the level of the levitation fluid.
In particular, ESPCI Paris study author Emanuel Fort said the research came out of a scene in the 2007 film Pirates of the Caribbean: At World’s End when a Captain Jack Sparrow’s Black Pearl ship was wrecked.
It also draws inspiration from Japan’s 21st Century Contemporary Art, Contemporary Art, ‘Swimming Pool’ at the Museum of Kanazawa – a quirky art installation.
“We were playing around – we didn’t know it would work,” Fort told the Guardian.
‘The funny thing is that it stimulates the reactions of people who are not scientific.
‘It’s hostile. He talks to people about science fiction and fiction and that’s great. ‘

Under the action of gravity, the viscous liquid in the container, such as the laboratory flask, will usually come to the bottom of the vessel.
Flipping the lid container will cause the liquid to slowly fall to the bottom under thick drops, such as the paint falling down the wall.
But holding the liquid in the air can be achieved by shaking the container vertically.
Scientists already knew that even vibrations of liquid at certain frequencies and in closed containers could be lifted above low gaseous levels, such as air cushions.
Thanks to the vibration, instead of growing air bubbles in the lower half sink.
In their experiments, the team filled a container filled with either glycerol and silicone oil and used shaking devices to vibrate the liquid evenly at high frequencies.

They applied air to the base of the system until they began to levitate when the fluid vibrated.
Air bubbles immersed in the liquid as expected, as expected.
But small objects, up to 7 grams in mass and up to 0.9 inches (2.5 cm) in length or diameter, floated up and down in the lower part of the air and liquid where they were found.
This is because the level of air and the level of the floating liquid at the bottom of the airtight boat have a very high pressure, as it is compressing with the weight of the liquid.
This resulted in the boat coming under pressure from the bottom.
Holding the liquid in the container in the air can be achieved by ‘vigorous vert shaking’.
When that pressure is balanced with the force below gravity, the boat floats.
At that point, the boat has its own radiant power that keeps it afloat.
Tical shaking also causes a boom in the lower surface of the levitate fluid, as if its gravity has been reversed.
Buance is a force produced by a liquid that resists the weight of a substance immersed in a liquid.
Vladislav Sorokin of Vib Kalend University and the Russian Academy of Sciences, who were not, said, “The abnormal behavior of vibrating fluids is usually a small fraction of the surprise phenomena that result from high-frequency vibrations.” Engage in study, write in the accompanying part in Nature.
‘[The research] Suggests that many significant phenomena occurring in vibratory mechanical systems have not yet been publicized and explained, especially at the interfaces between gases and liquids. ‘
Observations made by Fort and his colleagues refute Archimedes’ theory that a force equal to the weight of the displaced fluid is applied to the body.
The study is published in Nature.
