The video explores the fascinating phenomenon of fog rings created by volcanoes, comparing them to the fog rings humans can make by exhaling on a cold day. It explains the concept of vortex rings, which occur when fluid is dragged and swirls, forming rings. The video discusses how volcanic vortex rings form when trapped gases in magma escape explosively, creating visible rings. This research helps scientists understand volcanic structures. The video concludes with a promotion for the SciShow calendar featuring images from the James Webb Space Telescope.
