Scientist have done what was once thought impossible, they have floated a toy boat upside down on levitating liquid, and they did it by accident.

The liquid is made from silicon oil and glycerol and is suspended in air by quick vibrations that forms a cushion of air underneath it, allowing the boat to float.

This is a balancing game between the boat and the air cushion because gravity is still pushing down on the liquid.

If a person pushes down on the boat while it's floating upside down, it will fall into the air cushion below. 

And if that person lifts it slightly, it would float to the top.

This discovery by researchers at the Langevin Institute in Paris happened by accident. 

According to Benjamin Apffel, a first year PhD student and a researcher on the study, the scientists were first just interested in the floating liquid. 

"We were just playing around with the experiment...And so we were wondering what what would happen if we put [a boat] on the [surface]? 

"At some point to we pushed at little bit too hard. And it went on to [underside of the liquid] and it was floating, and then we were wondering okay what's happening now? 

"Why is this possible? Is it real or is it just some strange effect?" 

The research published in the article 'Floating under a levitating liquid' is still at its beginning stages.

However, early speculation suggests that one day people can use this technology to separate water from pollutants. 

It may also be used as a measuring tool to sort through different objects based on weight because heavier items will start to fall first if the vibrants are lowered slightly.
