    This video explains why I had a blue splodge on my face in the last video! The sponsor is 80,000 hours. Head to 80000hours.org/steve to start planning a career that is meaningful, fulfilling, and helps solve one of the world’s most pressing problems.

    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.
  • This shows the difference between physical and digital simulations. In digital there is always something overlooked like the ire pressure in this situation which is why its always important to test the digital one on a small scale first.
  • 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.
  • Realizing every maze has two halves was a surprising revelation I didn’t expect.
  • 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!
  • @lazydk2654
    Regarding the 2 paths leasing to 3 walls you can 'hug'. It still works holding the hand on a wall, if you do so when you enter the maze. The 3rd middle part that loops wont be one of the walls at the entrance. So unless walls are shifting its a pretty safe approach

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

    Nice, now the alligator can finally have his shower

    If you get stuck in the Backrooms- just flood it

    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.

    Maze-solving algorithm for red water: 1. Find someone who solved the maze with blue water 2. Copy their homework
  • @triffinne
    I came here from the short to ask what would happen if you put dye in after it was solved, very glad to see that it worked exactly as I expected! Thank you for doing more than just answering the face question and thinking of more interesting things that can happen in the situation!
  • 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.
  • @__-cd9ug
    That last part is so interesting. Blue water has figured out the maze and now the red water can go directly to the end with virtually no loss
  • @100StepProgram
    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
