So a Liquid Can Solve a Maze How Exactly ?

Under things I never thought I would ever read, apparently there is a type of liquid that can solve a maze. Surely that is not real. But it is. If you want to make a guess what 3 things make up this concoction do it now.

The "Intelligent" Maze Solving Liquid

  • How it works: Scientists have created a liquid that can navigate a maze without any external guidance. This "intelligent" liquid is a mixture of soap, milk, and ink. The key is the combination of surfactants (found in soap and milk) which create a resistance gradient that guides the liquid along the correct path.

  • Surface Tension: The driving force behind this phenomenon is surface tension. Surfactants reduce the surface tension around the ink, initiating movement (Marangoni Flows). The milk adds another surfactant, creating a "landscape of varying resistances" that helps the liquid find the most efficient route.

    • What are Marangoni Flows?

  • Surface Tension Gradients: Marangoni flows are the movement of fluids caused by differences in surface tension. Surface tension is the force that holds the surface of a liquid together. This movement caused by surface tension gradients is what allows the intelligent liquid to navigate the maze.

  • Causes of Gradients: These surface tension differences can arise from:

    • Temperature Gradients: When some parts of a liquid surface are warmer than others, the warmer areas have lower surface tension.  

    • Concentration Gradients (WHAT WE ARE DEALING WITH): Variations in the concentration of substances (like surfactants) across a liquid surface also lead to surface tension gradients

  • Potential Applications: This discovery could have significant implications for fluid transport in complex systems, such as drug delivery within the body or improving lung health.

This is not the only way a liquid can solve a maze, but it is the most interesting! While the 'intelligent' liquid utilizes Marangoni flows, other liquids can solve mazes through different scientific principles. Here are 2 other known ways liquids can solve mazes using science.

Other Maze-Solving Liquids

  • Chemical Reactions: Some experiments use chemical reactions to guide liquids through mazes. For example, a liquid containing a chemical that reacts with a substance placed at the end of the maze can be used. The reaction creates a "trail" that the liquid follows.

  • Acids and Bases: Another approach involves using acids and bases. By placing an acid at one end of the maze and a base at the other, a liquid containing an indicator (a substance that changes color in the presence of an acid or base) can be guided through the maze as the acid and base neutralize each other.

Important Considerations for Creating Liquid Mazes

  • Maze Design: The design of the maze plays a crucial role in whether a liquid can solve it. Simple mazes with clear paths are easier for liquids to navigate, while more complex mazes may require specific liquid properties or chemical reactions. This sounds similar to how humans solve mazes!

  • Liquid Properties: The viscosity, surface tension, and chemical reactivity of the liquid are all important factors that determine its ability to solve a maze.

  • Experimental Setup: The way the liquid is introduced into the maze and the overall experimental setup can also influence the results.

Maze Comic Book Cover #73 - Bark to the Future

Issue #73 in my comic book cover series is called Bark to the Future and features the maze of a dog, specifically a Rat Terrier. The DeLorean was made using ai. Who do you think would be the “Doc” in this comic ? Another dog ? An owner ? And what would the dog’s name be ? Marty McDog ? Thinking out loud.

My comic book cover mazes can be found in 2 places:

Comic Book Cover Mazes - Year 1 (Issues #1-53)

Comic Book Cover Mazes - Year 2

Rat Terrier Maze Comic Book

To receive a book of my first year of comic book book mazes (Volume 1 with mazes #1-53) you can sign up for my book alerts - any time I launch a free maze book, or paid book (on Amazon), I will send you a note about the new book launch.

Maze of the Week 46 Redux - The Free Stamp (MOTW#177)

I think of all the maze updates I have done this is the most different before and after. The initial maze was simple and easy. It could easily be solved by children. For this project the maze did not change, but the surroundings certainly did. Here is my original post:

Maze of the Week #46 - Free Stamp Maze

Here are the enhancements I made to improve the maze:

1. Added the Ground. The maze was floating on the page but no more.

2. Changes Pathway Size. I widened the pathway transitions between colors from anywhere between 50% to 150% so they can be seen more easily.

3. Title Changed. I added the park name, and changed font sizes of labels.

4. Color Changed. I changed the color of the stamp to an off white from pure white to better match the true color of the sculpture.

5. Added Structure Details. I added the stabilizing structure on the ground below the stamp.

6. Arrows Replaced. I replaced the arrows with a written start and goal to allow me to create background items more easily.

7. Changed Size. I reduced the maze size (height minus 1.5 inch) and re-oriented everything down half an inch to reduce the grassy area and sky portions.

8. Added Background details. I added many trees and bushes to the background which are textured. The trees include leaves. I added the large building in the background with color and window details. I may have put more work into the building than the original maze ! If you are a Clevelander you know the building. I added the wall behind on back right bottom between the street and the building. I added the sky. I added the sandy area under the stamp near the new support. All of these things make a more realistic maze.

9. Added Shadows. I added a shadow on the ground from the stamp and another from the largest tree.

This is a big unveil. Before and After:

Looks and feels like a totally different maze to me. I prefer the new one by a wide margin !

Some data: The new file is 1,210MB from 59MB.

I will be replacing the homepage with the new maze going forward. You can find the maze download there !

Introducing 8 new free printable maze sections to the website

I have been working on new mazes for a few months. Instead of introducing them a little bit at a time like anormal person I am launching a large amount all at once. All of them will sit in the Free Printable Maze section of the website. This email is to tell you what you can expect there. One thing I can safely say is this is a wide variety of mazes.

Here are the 8 new sections of the site for Kids: Some are not labeled as being for kids, but the level is beginner and they are the target audience.

So that is 203 new free downloadable mazes, with 7 of them available in book form ! Here is one of each type to give you an idea what each is:

I hope you enjoy the new mazes. There are more to come !
