In what way is it not?
The movement of water molecules is typically much slower than the wave speed of water.
When you turn on flow to a filled pipe, the water is reluctant to enter the pipe faster than other water is leaving the opposite end (mediated by pressure waves).
- Smoosh 4y agoMainly because the maze is empty to start with, and the water must flow simultaneously to all points equidistant from the entry until the exit is "found".
- roelschroeven 4y agoThe analogy would work better if the maze would start with entrance and exit closed, and filled with water to half height. IIRC the author mentioned this in a comment under the video.
- martyvis 4y agoAt one point in the video, he appears to splash clear water into the filled maze. You can see the non-moving parts lighten their colour compared to the active path.
