Discussion Overview

The discussion revolves around the observation of a spiral piece of wood moving in a stream, as shown in a video. Participants are exploring the mechanics behind its movement, particularly in relation to the second video where the wood appears to move upstream when water is poured into a container.

Discussion Character

  • Exploratory, Debate/contested

Main Points Raised

  • One participant suggests that a string might be involved in the movement of the spiral branch, noting that it appears to be pulled along.
  • Another participant agrees with the idea of a string, emphasizing that the movement resembles being towed and points out the presence of a wake.
  • A further comment mentions that illusionists often use fishing line, which is invisible to fish, to create similar effects.
  • One participant asserts that the discussion should not continue if it involves debunking pseudoscience or fake videos.

Areas of Agreement / Disagreement

Participants express differing views on the nature of the videos, with some proposing the involvement of string while others question the validity of the videos themselves. The discussion remains unresolved regarding the actual mechanics behind the movement.

Contextual Notes

There are assumptions about the visibility of potential strings and the authenticity of the videos that remain unaddressed.

Hi I have found a video which is composed of 2 videos. In the first one you can see that a spiral branch is put into a stream and starts to move by itself in a snake like motion.

In the second video similar spiral piece of wood is floating in a container and then water is poured into it and it starts to move upwards the stream of water. How's that possible? Thanks

i wouldn't be surprised if a bit of string was involved.

That was my thought too. I can’t see the string, but it certainly moves as though it were being pulled by string.

The first one, in particular, seems like string. There is a wake, and they carefully avoid showing the front end of the stick before it is submerged.
 
Illusionists use fishing line. Fish can’t see it either.
 
Since we don't debunk pseudoscience or fake videos, thread is done.
