Vortex rings What do dolphins, humans and volcanoes have in common? They can all produce toroidal vortices of course! Surprised? Grab some food colour and a glass of water to find out how.

Vortex rings are pretty cool, and electromagnetism even cooler. Now, a team of physicists have found a way to combine the two phenomena, creating the electromagnetic vortex cannon. In fluids ...

"The vortex rings generated by the sneeze capture the microscopic droplets within the sneeze and transport them to the top and bottom edges of the face shield," Akagi says.

Mount Etna—located in Catania, Italy—is one of the rare volcanoes that can blow out rings of gas and steam. Known as volcanic vortex rings, the phenomenon only occurs under special conditions ...

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 ...

The rare phenomenon, known as “volcanic vortex rings,” is generated by the combination of rapid gas release and the vent shape spewed out of a new crater that opened on Tuesday on Etna’s ...

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 ...

When practicing, recovery should be initiated at the first sign (lightness in the seat) in the incipient stage of the vortex ring. Part 3 of this feature discusses three ways to avoid VRS state.

Vortex rings, a mysterious and fascinating natural phenomenon, display breathtaking structures and behaviors in both air and electromagnetic waves. Imagine an air cannon that can shoot vortex ...

Topological monopoles are a quantum physics phenomenon that can decay into what’s known as “Alice rings.” Named after Lewis Carroll’s famous heroine, this vortex ring flips the magnetic ...
