This video explains why I had a blue splodge on my face in the last video!

You know what I think can solve the puzzle flowing through the main path right away?? Smoke! Pushing smoke into the puzzle, it will flow through the path of least resistance from the start

Regarding surface tension, try solving the smaller maze with 'wetter' water. Reduce the surface tension of water by dissolving some alcohol in it. :) Might be interesting with different fluids as well.

Directly to the experiments in less than 1 minute, now this is the channel that deserves to be popular.

Nice, now the alligator can finally have his shower

the fact that a maze is two separate pieces blew my mind more than the water maze. It makes perfect sense but I have never thought of that!

[thomasschmidt]

Realizing every maze has two halves was a surprising revelation I didn’t expect.

[billyruss]

I had never thought of a maze being in two halves - and yet it's so obvious when you think about it! Steve is like the Johnny Ball of the digital age 🙂

Maze-solving algorithm for red water:
1. Find someone who solved the maze with blue water
2. Copy their homework

There are couple of important things this experiment shows, especially when dye is added. It shows what happens when there are unused lines in water delivery piping (like for example building hydrants sharing same line with tap water). It can become breeding ground for bacterias, eg. Legionella, despite water moving, and that's why it's important to use backflow prevention valves.

The "keep your right hand on a wall" always works, IF you start doing so from the entrance!
A maze may have two or more paths to the exit and therefore has more than two wall structures, but it will always have just two outside ones.

I loved the solution of cutting slots in the upper acrylic plate to allow the solvent to reach the surfaces you wanted to solvent weld.

Someone should make a free demo and share or code for a 3d simulation, this could be in unity or unreal or something like that.

Regarding using the "hand on one wall" method to go through a multipath maze, as long as you pick a wall right at the entrance then you should still always find your way out. Any extra paths would create a third piece to the maze, but by necessity it would have to be in between the two outer parts which must be the two parts bisected by the entrance and exit.

[webkinskid]

man, you really nailed the lighting on the larger mazes, the contrast of the "walls" is perfect

[StepProgram]

This is the first video ever where I saw the short, thought it was cool and actually watched the real video. That’s how good your content is

[donaldasayers]

With your second complicated, big maze, I don't think it is surface tension but an air lock, the path repeatedly goes up then down so if there is a bubble in each up bit, it requires a minimum head of water to overcome the sum of the uphill parts.

True,
if you only start using the 'hand on wall'-tactic as a backup plan, after you've already been in the maze for a while a multi-solution one can trap you.
Doing so from the start will work (for any 2 dimensional maze, where 'out the other side' is the goal. Get to the centerpiece artwork (or staircase to the exit-tunnel), are made out of 1 piece and may loop you back to the entrance )

If you get stuck in the Backrooms- just flood it

5:28 Even in a multiply-connected maze (one with multiple successful paths), you can be sure that the walls of the ENTRYWAY will be the walls of the exit, as long as the entry and exit are on the outside border of the maze. I didn't realize that until you showed your "coloring the walls" at 2:50 then mentioned that two paths would create a middle part. That middle part won't be the left or right wall of the entrance, but would necessarily be an "island" in the middle. The interesting thing is that you can't just wander around and decide later to use this algorithm: you need to commit to it at the very entrance to the maze. And, it only works if the exit is also on an external wall, not say a stairs in the middle of the level, or say a goal or treasure of some kind not adjacent to an exterior wall.
