I just have to say, I really appreciate how humble u are! U always say, "my first attempt" instead of automatically thinking u are gonna solve it. Also, that hydrophobic maze was really neat!
I love how not only do you solve the puzzles but you break it down in simple terms (I.e. breaking out your notebook, drawing diagrams, explain complex words, etc)
im an engineer graduate and that hydrophobic surface explaination is perfect if u replace (surface tension ) with (porosity) because surface tension is a water property while porosity is a surface property. good explaination nontheless and keep up the high quality videos as per usual
What exactly _porosity_ (BTW, is it not a surface property, it's a material property) has to do with hydrophobic properties? It has zero relation to this. His explanation was actually correct, there are three phases of matter (gas - solid - liquid) which comes into contact and this effect basically takes place when surface tensions between any two of those in equilibrium are related in a certain way. If a solid-liquid and solid-air surface tension coefficients are equal - which means that the forces and energies per surface unit on the borders between those phases are equal - then the droplet will be a perfect half-sphere (90 degree angle). It can be interpreted as the solid "sees no difference in what to stick to" - air or liquid. If a solid-liquid and air-liquid coefficients will be equal then it is an absolutely hydrophobic surface - 180 degree angle with almost zero surface betweem solid and liquid, the droplet will want to be a perfect sphere, minus gravitational distortion. There will be almost (because it is a normally unachievable extreme case) no difference in energy per surface unit between those phases related to liquid, which basically means that the liquid "sees no difference in what to stick to" - air or solid. Both coefficients are equally insanely high in this case related to the third air-solid coefficient, which is low, and in turn, this means that the solid "wants to stick to air but not to liquid", which results in mentioned almost zero solid-liquid surface, shrank by surface tension forces with those insanely high relative coefficients. And also, in reverse, you can *make* the surface of solid behave like this by limiting the surface area between solid and liquid artificially - which is actually how lotus flowers works, their surface has nanoscale needle-like crystal structures which "support" the water droplets on their tips and prevent them from sticking to the main surface area of the leaves. Well, I guess you can already see *why* it was mentioned as complicated by Mr. Puzzle)
He mentioned that the maze has a waxy hydrophobic surface…Hydrophobic materials have almost all, or perfectly, neutral covalent bonds. Water is a polar covalent solvent so it forms intermolecular bonds (like hydrogen bonds, or van del waals forces) with almost any material with ionic or polar covalent bonds. Water is also called the universal solvent. So the surface of the maze must be covered in a material made of perfectly neutral covalent bonds creating a surface to which the water molecules could form no attraction other than to themselves (hydrogen bonds) which give you cohesion/surface tension on more area of the droplet forming a near perfect sphere which has the lowest surface area to volume ratio.
I think I see why your solution works better than the "official" one. The freeplay between 9/7 and 9/8 is just barely enough to squeeze either 1 or 2 in either gap, but since 7 is ever so slightly smaller than 8, the ever so slightly larger 2 fits more comfortably between 9/7 than 9/8. Since 1 is so small it could, as you so capably demonstrated throughout the solve, fit in the gap between nearly any of the larger pieces so it doesn't matter which side of 9 it goes, it will have plenty of freeplay either way.
If you place a straight line through the center to connect the edges of the frame (any direction) you see that the sum of number on that line is 23. If we assume the numbers on the circles are a sign of proportionality then you can easily solve this after putting 10 in the center (and number 1 and 2 you just insert them at the end).
@@anthonycannet1305 after. The configuration at the begining before you put the dime in is just a random configuration. When you use 23 as the sum of the line through the center you cover the most of the free spaces between the circles on that line. If you use 20 like in the begining, or even 21 you will see that the free space between the circles is much larger, but not enough large to fit the smallest piece. I was just looking if I can find some pattern based on the solution that can be mathematicaly explainded and make sense.
@@ivanmodesto7947 - Your proposed idea of adding up to 23 doesn't work for the 1, 2 or 3. Also it would mean that the 3 and 4 would need to be transposed.
I really appreciate your comments at the beginning about time limits. My wife and I do escape room board games together like Exit and Unlock, and they usually come with a time limit of a couple hours that we ignore. We are both very smart and good at these puzzles and yet they tend to take about twice as long as the time limit. I figure they expect that once you've been stuck for a few minutes, you will look up the solution, but they are so much more fun when you actually spend the time to puzzle them out!
@@andrewgarner2323 And anytime someone makes a generalization that broad, they are wrong. Book smart wise, I have a very strong scholarly background, so I could probably objectively be called smart. However, book smart only matters so much in this context so I probably should have used a word other than "smart" in my original comment, as it wasn't quite the right nuance. So maybe my wording wasn't quite smart there :P I really meant more that my wife and I come from a strong background in solving puzzles.
You may not know this, but way back in the 1980s, there was a maze puzzle available from toy shops, aimed at kids, made of plastic and containing a blob of mercury! Wasn't that a bit dangerous? It was only dangerous if you broke it ..... Using a special water-repellent surface coating that makes water behave similarly probably is a lot safer, and certainly no less fun than the classic mercury maze -- probably even slightly more interesting, if anything, for knowing that it's just a blob of water with some pigment that you put in it yourself .....
Yes, I had one of those maze games! It was called "Quicksilver". But it was fully contained and think about: we used to have thermometers filled with mercury as well as thermostats and other devices around the house.
Great video as always! Wouldn't it be a good idea if the central circle of the hydrophobic maze was non-hydrophobic? Once the maze is solved the drop would splash (proving it to be just water) and maybe drain through some holes...?
5:59 Knowing the solution cannot be revered. I wouldn't say that it's true. It's been four years since I watched puzzles like Tricky Dick. When you did it I then knew how to solve it the next days. But now it's been so long that I've completely forgotten how to solve it.
@@robertlozyniak3661 - you can get it from the old school blood pressure pump-up cuff thingies. They come in a folding metal box, which when opened contain the glass column with quite a large Mercury reservoir. Great for innovative cocktail drinks!
I got one of these hydrophobic wooden mazes in a box from Chris Ramsay, and thought it was super cool! I'd love to see you and Chris puzzling together sometime! He does some seriously wild sequential puzzles that I bet you'd lovr and I think it would be cool to see you two work together. You'd be amazed by his puzzle collection as well. Too bad he's in Canada and you're in Germany. :(
I say there are at least 4 solutions, depending on what is considered a unique solution there are the two, the official one and the one found in the vid. But one can also flip those solutions into a mirrored version. making two more debate-able solutions
I lost all respect for that puzzle as soon as you showed the message. Is that any better than the ad's on mobile games saying "99% of players can't pass this level"? By the time you see the message you already own the puzzle so why bother? I loved the hydrophobic maze though, that is so cool! Such a simple object but fun to see it in action :)
what would be cool is if the center of the puzzle was not hydrophobic and it just turned into a puddle when it hit the center. that would be super cool!
At 7:42 I was screaming to swap the 7 and the 8. I think that would create enough gap for the 2 to fit between the 6 and 9 or 9 and the now 7. I could be wrong, but check it out and tell me what you think. How many solutions do you think there is?
I think based on the mathematical solution there is probably only one. Since the puzzle has some free play to make it possible to assemble there might be a few more. At least two as I saw.
I think you prefer physical puzzles cause you get a commission from the sales but how would you feel about every once in awhile doing a puzzle from a video game.even just a short one would be cool for something different
If you take one number and add the number opposite to the 10 you get 13. So this is basically the idea for arranging the first numbers. To get as close to the diameter as possible.
Nope, not in English... the word is certainly not pronounced "SURF-ACE", but it's more close to SIR-FACE than SUR-FISS. Since it's blended together and said quickly, the result is more like "SUR-FUSS". th-cam.com/video/bCdYYRFJwso/w-d-xo.html It relates to a plane or FACE (of an object) hence why it uses that word "face".

That editing break at 5:40 is a bit sus. Is that when you switch out the red ball for the water drop?
Nope, it's just an editing break to mess with the week minded.

This has nothing to do with commissions. I just prefer the good old way to handle a puzzle instead of sliding my finger over a touchscreen. 😉
Are the diameters of the pieces related to their numbers? That is, is 10 a 10mm piece and 9 a 9mm piece?
Yes, each piece is the surface area increased by the surface of piece #1. Forgot to mention that.
Awesome puzzle and i like you to describe in a future video how to solve the rubik's cube I've never been able to solve it.
Why isn't there an app for puzzles like this? I can't afford all these wooden puzzles.

Didn't you do one like this a little bit ago same concept
Some well-intended language help: In English, the second syllable in the word "surface", though spelled "f-a-c-e", is pronounced "fiss" - not "face".

Since it's blended together and said quickly, the result is more like "SUR-FUSS".
