'Water tweezers': New technique generates topological structures with gravity water waves

A team of physicists at Fudan University, working with colleagues from Henan University, both in China, and from Nanyang Technological University, in Singapore and Donostia International Physics Center, in Spain, has developed a way to generate topological structures in surface water using gravity water waves. In their study published in Nature, the group used their technique to generate structures such as wave vortices, skyrmions and Möbius strips.
