Physicists sailed a boat upside down in a floating liquid ocean

It’s like something Stranger Things, But less demogorgon, less ominous darkness: Physicists created their own “upside-down” by inverting the reality and floating a small boat under a floating liquid.

Seeing it in action, you would think you’re seeing some sci-fi effects, but it’s all about the power of vertical vibrations. It is well established that liquids can remain suspended in the container due to carefully adjusted vertical shakes, and the team uses this phenomenon.

This new study shows that not only can suspension be achieved, but the lower half of the chamber can create a force balance similar to the upper half. Placing it on an upside-down surface of viscous liquid leaves a small model boat or ball intact.

“When placed on a less dense medium, a layer of liquid usually collapses downwards when it exceeds a certain size. This is because gravity acting on the lower liquid interface Rayleigh-Taylor instabilityThe researchers wrote. paper..

“Among the many methods developed to prevent liquid dripping, vertical sway has proven to be efficient and is studied in detail.”

“We theoretically predict and ly show that vertical wobbling creates a stable buoyancy position at the lower interface of the liquid, which behaves as if gravity was reversed. Objects can float upside down at the lower interface of a floating liquid layer.”

What really happens here is that the boat (or similar object, if small enough) is pushed into the liquid. This is due to the high pressure in the underlying air pocket, the pressure created by the weight of the first liquid layer. ..

When the upward force of this pressure balances the downward gravity, the object floats on the upside-down surface. Balancing that pressure is a difficult part and this is one of the main topics of this new research. The required force was mathematically modeled before being tested in the laboratory.

The strange effect remains stable when the boat is pushed or pulled (in this case via the magnets used through the glass of the container). Regain equilibrium, as if you were rocking with the right side of the lake up.

The intensity and frequency of the shaking is very important for this trick to work. As the vibration diminishes, the magic is released and both the boat and the floating liquid layer fall to the bottom of the chamber (see the video above for details).

However, this is not just a clever party trick. Findings can have a variety of uses, such as transporting gases and other substances through the fluids of industrial machinery. For now, it’s fascinating to see how fascinating it is to look like magical physics.

The research is published in Nature..
