This stick is of a Plant in the Himalayas called Garud Kashtha meaning Eagle Wood in Sanskrit; it is helical and moves against the flow of water horizontally or vertically; I wonder if plants use it for the transport of pollen, seeds, or migration?

@micromotility reference-less video probly fake? commenters can find no infos on it. u work on this kind of physics? is it at all possible?
@barrygoldman1 well yes indeed the video is probably fake but it's a nice concept to think about...
Dead fish have been shown to "swim" upstream but elasticity is required there which doesn't apply here ..
@micromotility ok a sailboat can tack up wind and by switchig back and forth ... build the simplest mechanism that can do this. does it need two phases (water, air)?
@micromotility wait, WHAT? do FISH use some of that physics to help swim upstream? whats going on here
