... rapidly that when obstructions such as rocks are encountered, the water can splash sideways, upward, and/or form swirls and eddy currents. This chaotic motion of the water can cause some of the water to momentarily move “upstream.” Another artifact of water in turbulent flow is that the water...

... appearance of floaters in your vision. Floaters are those swirling distortions that occur randomly in normal vision, most often after a blink or when eyes have been closed for a couple of seconds. Floaters are caused by dead cell tissues that detach from the retina and choroid, and float...

... of the wing. Vortices are formed at the wing tips, which produce a swirling flow that is very strong near the wing tips and decreases toward the wing root. The local angle of attack of the wing is increased by the induced flow of the tip vortex, giving an additional, downstream-facing, component...

... to roll around the inside easily when the balloon is inflated. Try this yourself to make sure they are the right size. The most stable orientation (least energy scenario) for the nickel inside the balloon is the rolling state when the balloon is swirled. This is probably due to the friction caused when...
