In the lab's experiments, the ball was floating on the surface of a large tank of water, and its position was captured by an overhead camera. Audible soundwaves emitted from a speaker array at either ...

Researchers have succeeded in directing floating objects around an aquatic obstacle course using only soundwaves. Their novel, optics-inspired method holds great promise for biomedical applications ...

Researchers manipulated water waves to move ping pong balls with a level of precision that seems straight out of a sci-fi movie. Reading time 3 minutes Imagine hopping onto a large floatie in a lake ...

Summer brings with it the sight of surfers moving seamlessly across wave crests, with ocean waters carrying them along ...

In a nutshell: Researchers from Nanyang Technological University in Singapore have demonstrated the ability to manipulate water waves, allowing them to precisely control objects floating on the ...

Host Lloyd Liedtke guides students through hands-on experiments exploring buoyancy, balance and force. Learn why some objects float while others sink, how paddle boats move, and how weight and volume ...

A new study has recorded hydrodynamic levitation in action, revealing objects gliding on liquid surfaces without direct support. High-speed footage shows fluid motion creating enough lift to ...

In 2018, Arthur Ashkin won the Nobel Prize in Physics for inventing optical tweezers: laser beams that can be used to manipulate microscopic particles. While useful for many biological applications, ...
