While something called a "vortex gun" might sound like a device from science fiction, the fact is that they have been available as novelties for years - if you've ever used a toy gun that shot out a ...

The study of vortex ring dynamics centres on understanding the formation, evolution and decay of toroidal vortices generated by pulsed fluid jets. These phenomena are crucial in a wide range of ...

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 ...

Some of the world’s most important discoveries – penicillin, vulcanized rubber and Velcro, to name a few – were made by accident. In fact, it’s been said that upward of half of all scientific ...

COLUMBUS, Ohio–Scientists at Battelle have filed a patent application for a device that shoots out rings of gas–an invention that could aid firefighters in suppressing smoke as well as delivering a ...

Researchers have observed three-dimensional magnetic vortex rings in a real-world magnetic material for the first time. Contrary to theoretical predictions, these rings – which are spin configurations ...

Toymaker Wham-O created the Air Blaster, a plastic pistol equipped with an air pump and a large funnel in place of a barrel, in 1965. The lucky kid who owned one could fire a powerful ring of air that ...

Vortex guns capable of firing doughnut-shaped rings of air have sat around as toys or oddball gadgets for years. Now a U.S. lab has added an extra kick with electrically charged rings that could clear ...
