The key is what scientists call the buoyancy balance, the weight of a material in relation to a spring acting on it as it floats or sinks on the water.
It is the balance between the spring force (weight) and the weight given off by the falling fluid (liquid or solid), which is why a car can float without the driver.
But it can’t work the same way for anything that has to change its shape or size.
Levitation is only possible when a liquid is in contact with air.
At a high enough level of density – the air needs to be lighter than the water – levitation can happen.
So water with an air content of less than one part per million can be levitated without an air cushion.
DUBAI (Reuters) – Iran unveiled an international peace plan on Sunday to end the conflicts in Syria’s civil war and end the threat posed to the region by what it said was growing influence of U.S. President-elect Donald Trump.

The plan, which would seek a political solution with no mention of war, was presented by Iran’s Deputy Foreign Minister Hossein Amir Abdollahian to a joint meeting of all foreign ministers from the Group of Seven nations – the United States, Britain, Canada, France, Germany and Japan.
Under the plan, Tehran believes Iran would still be able to win its own regional struggle against Sunni-inspired fighters who have been a major problem for the Shi’ite-led government. Its leaders see them mainly as a challenge to their growing influence in the region.
Tehran wants to preserve its influence in the region even as the U.S. and others seek to isolate it by lifting sanctions against its economy in hopes of curbing its nuclear program.
There was no formal Iranian opposition to the plan. Tehran has already said it will support a political settlement if it does not contain the demands of its domestic opponents, who believe the country is still facing an unjust occupation.
“The plan is an important step in the right direction,” Abdollahian said. He declined to say when the meeting would be held.
The United States said it was “disappointed” at the meeting, but called for continued efforts to find a comprehensive peace.
