Simple physics . Buoyancy determines whether an object submerged in water or surrounded by air will sink, float, or stay put. Buoyancy is what keeps ships afloat and balloons afloat.

Where there's water, there are waves. But what if you could bend water waves to your will to move floating objects? Scientists have now developed a technique to merge waves in a water tank to ...

The scientists placed a small floating polyethylene foam ball in the water tank and observed how the ball moved when the waves were produced. Balls ranging from 4.8mm to 12.7mm in diameter were ...

An international team of researchers has developed a technique to manipulate water and move floating objects with a level of precision that seems right out of a sci-fi movie.

Waves and water are inseparable—but what if you could manipulate the waves to move floating objects? A team of international scientists, co-led by Singapore’s Nanyang Technological University ...

A new approach to invisibility cloaking may one day be used at sea to shield floating objects – such as oil rigs and ships – from rough waves. Unlike most other cloaking techniques that rely ...

A water-based tractor beam that could contain oil spills and manipulate floating objects cannot yet be explained by mathematical theory. Michelle Starr is CNET's science editor, and she hopes to ...

A team of international scientists co-led by Nanyang Technological University, Singapore (NTU Singapore) have discovered a way to manipulate water waves, allowing them to trap and precisely move ...
