Better understanding the formation of swirling, ring-shaped disturbances—known as vortex rings—could help nuclear fusion researchers compress fuel more efficiently, bringing it closer to becoming a ...

1. Fill a tall glass to the brim with water and wait for at least 30 seconds. Even though it looks still, water keeps swirling for ages so the longer you wait the better. HINT: Use an eye-dropper if ...

Vortex rings are toroidal structures of fluid characterised by closed-loop vorticity that provide a compelling example of coherent structures in fluid dynamics. Their dynamics involve complex ...

Air rings blown by dolphins swimming underwater and rings of smoke emitted by jet engines are just two examples of vortex rings. These doughnut-shaped structures and their mesmerizing movement have ...

YouTuber's Destin Sandrin, who has published a lot of science education movies, has been trying to compare the way the vortex of the northern hemisphere and the southern hemisphere wraps backwards, ...
