They tested floating polyethylene foam balls (4.8mm to 12.7mm in diameter) and a 40mm ping pong ball, observing their movement in response to the waves. By adjusting wave magnitude and frequency ...

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. Beyond its inherent ...

Some patterns acted like tweezers or a 'tractor beam' to hold a floating ball in place. Other patterns made the ball spin and move precisely in a circular path.

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 ...
