The Steel Ball Paradox! - An Impossible Puzzle! (almost) 

Another time it seems I found a new and unique "Mr.Puzzle Solution". However, it was faaaaar away from the intended solution. Want to see it in a future video? Vote below! Keep on puzzling everyone and have a nice weekend!

The inertial solution is brilliant because the first little one misdirects you.

"It's obviously sandblasted." Had no idea how incredibly ignorant of telltale sandblasting I was.

That gasp on completion was incredible hahaha

For a film I worked on we actually used the Buddha ball to balance a small candle that had a mettle base with a slight spin to give it a futuristic look. It was really cool to have a floating candle in the background of a scene.

I think the intended solution is the very clever one you found last: to unscrew the acrylic sheet cover.

"It's truly been... a roundabout path. Thank you... Gyro."

I was sitting here tilting and rotating and turning my phone like I was trying to solve the puzzle...😂😂😂

I love how he takes it off camera for a minute and you can just hear him shaking the thing

It's hard to solve, yes. But how hard it was to design, that's what amazes me

Mr. Puzzle's laughter is so delightful. I never get tired of seeing what entertaining things, puzzles or gadgets, get showcased in each video.

I'm impressed how original a puzzle can be in 2021, yes please do the 2nd puzzle too! And what a lovely ball, pseudo perpetuum mobile!

7:55 - _"makes a mistake"_ Auto subtitles: *_"help me"_*

I'll never get tired of hearing "Hi! And welcome to another episode of Mr. Puzzle!"

2:40 "And if you solve the puzzle of how to get this in..." .. I actually grinned there ;)

Lmao when it jumped from 21 minutes to over an hour and to what sounds like him hitting it just made me bust out laughing

Wow this guy’s got balls of steel!

The small ball has less mass which means it changes direction and accelerates faster than the large balls because the larger balls have more inertia to overcome before they can change direction.

It's been so rare lately that you give a puzzle a 5/5! This definitely looks deceptively simple. Very cool. I'd love to see the other one.

Lol. The light makes the bigger ball bearings look like eyes 👀 😄

I was thinking about freezing it to make the metal balls just a little smaller thinking that was genuinely the solution

Sir, definitely show us the other one - not a lot of puzzles get your 5/5 rating, so the manufacturer definitely deserves more recognition. Doesn’t have to be a full episode, you can sneak it in as you did the magnet ball here, or many others. Always enjoying your content! No other puzzle channel can compare.

0:55 so “intriggering”... I like it, a mix between “Intriguing” and “triggered”. I think we’ve found a new word for something that’s curiously frustrating.

I'm frustrated and stressed just watching, lmao. This would drive me nuts.

Your real live reactions to solving all these great puzzles is what brought me to click that subscribe button a couple years ago. Please, keep on puzzling!!!

Your channel is one of my favourite places to go to calm down, get chill and comfy. Thank you Mr. Puzzle, keep on keeping on going

When Mr Puzzle says: "what can I do?!" you know you're in for a treat 🔥

“Do it again to make sure it is not a fluke” 😆

You've got the patience of a saint. Had it been me I would've hammered that puzzle to pieces out of frustration

as a phd in mechanics, i lift my hat off for this one!

Wonderful how you worked out and voiced that solution and then executed it moments later. Great to watch. Very impressive.

The inertia concept was really brilliant!

Me seeing the thumbnail: "just move the balls into the groove with your fingers so the small ball can pass, duh!" Me clicking on the video: "OH......"

it's actually not the speed that allows that solution, but the greater inertia of the two larger heaver metal balls that cause them to bounce in a slightly longer time than the small ball

I come back every 3 months or so and catch up. Happier and happier every time

apparently there is this thing where when we try to think of solutions to problems an important part of the creative process called Incubation is to go away and relax and focus on other things for a bit, its like it allows the brain to process it in the background

"keep in mind that knowing the solution cannot be reversed" My dumbass: "wanna bet?"

2:40 of frustration shouting at the screen: "Turn it so the window faces you!!"

So simple and beautifully crafted! Plus the design is genius! I will look forward to seeing you solve the other one

I love your videos. The pure joy and excitement noise you made felt justified. Its pretty good when such a simple puzzle can be so rewarding.

I'm glad you like dexterity puzzles cause I get to watch you solve them because I have _zero_ interest in them myself. much too fiddly for my tastes.

This was a damn good puzzle, I like that we can see exactly what’s going on. Personally I would love to see the other one as well. 😃

Beautiful Puzzle and Elegant Solution. Thank U, Mister Puzzle 🧩.

I love this channel!! It's so wholesome and I know I will always get quality content. Love the gadgets and puzzles and this time we got to learn a little German. 😁

I love this guy

From the first second on i felt like this could be a mindblowing airstream mechanic (with the airchannel at the bottom). I shortly realised that it would need more airholes for it.

This is the first episode I'm watching of yours. I really enjoyed it. 😁

Just another reason why I watch Mr. Puzzle. Puzzle solving and a science lesson all in one. ❤️👍😀

Best puzzle for a long time. Now they need to make a slightly bigger version with 2 or 3 more stops.

Intrigering 😂😂😂... love your videos!!

That reaction once he got it was awesome😂👏

I've been watching your videos for so long I always assumed I had subscribed and hit the bell. Realized today after quite some time I had failed. Fixed that right away! Cheers and keep puzzling!

Wow cool puzzle I enjoyed that one!

I was thinking getting the little ball sitting on the two large balls with the puzzle on it's side and then spinning it to force the two large balls up and out letting the small ball through might work.

easy. 1- leave the ball in the middle of the big balls 2-lift to leave the glass upright, and make a centrifugal movement 3- the big balls will rise and let the ball pass. 4-end

At 4:33 on your timer you answered how to solve it. The big balls always move faster! by getting the small ball close and then tilting back the big balls move back faster leaving the small ball ahead of them, you just needed to flick back and forwards at the exact right time.

That 1hr mark when starts shaking it in frustration had me

Alright the answer is simple, but first we have to talk about parallel universes

Man, just watching you do this made me tense. Thanks for the video.

This puzzle is ingenious. I had the idea of bouncing it before you actually solved it, but I wasn't sure the small ball would have enough springiness off the back wall, and that it would have enough momentum. I really wish I could get my hands on one of these!!

With the large ball bearings I was wondering if spinning it was the solution. As the centrifugal force would bring them outward giving room for the small bearing to fall in.

Watching this on a phone had me turning my phone all over the place trying to see what was happening.

Been a while since i commented by man that's a brilliant puzzle ...yet yourvmind is more brilliant !! Always in awe!!

I love when you laugh as you make me laugh too.😜

Could you put the box on it's side, with the small ball sitting on the two bigger balls. Then if you spin it the two balls will be forced outwards, and therefore upwards. The small ball will then drop down.

After about 5 minutes, I'd be digging in my drawer for a magnet!!! And just HOPE the balls are magnetic. lol

Idk how I got to this video in my RU-vid rabbit hole, but it’s quality content so I’m fine with it. Keep doin your puzzles man, you’re great

Fantastic! I love your channel so much.

I've got balls of steel! Which severely annoy me at this point...

Lesson: Just use a magnet.

Puzzles were you have all the information are, for me, the best ones. Now, puzzles where the puzzles is in part to be able to get some information out of it are nice too (like the labyrinth ones where you have to separate two pieces or roll a ball from one end to the other without seeing the maze). I have the Dr. Nim game and it can be seen as a puzzle. You can ask people how to beat it, knowing they can see all its working. Few people are able to solve that question although, the solution seems very obvious when told. I did interview and one of the problem I gave (and that I dropped, due to too many people failing it) was to write a winded piece of code that shuffle an array. The only thing to care about was that the code never use the values in the array to do the shuffle. That's one bit of the trick. The other is the same as with Dr. Nim. The question is, given the output, what was the input. Candidates do the obvious: write the algorithm backward in an attempt to be able to rune the shuffle backward and recover the input. The twist is that the shuffling code use modular arithmetic and a theorem of modular arithmetic. So, when they come to that part they are baffled because modulus basically map an infinity of values to one. (it's a very primitive hashing function) That should be a hint that the algorithm is "one way", but they never got the hint. So, here is the puzzle: how to solve Dr. Nim and that algorithm question ? (And the fact you don't need to know the algorithm gives a huge hint!)

Nice Video. Yes, I'd like to see the other one, too!

I was guessing that the 2nd part should be a spin move, with the small one in between, puzzle standing up so the glass is vertical. The rotation will force both big balls to move to the outsides, while the small ball in the middle gets pulled down by gravity

I think you should try rotational forces. If the axis is between two balls, you can make them move in different directions

Love the commentary, you are truly entertaining my friend.

Fantastic Puzzle - Great solution

Don’t get be books or t shirts for my birthday mom. Get me some puzzles!

Did anyone else find themselves tilting their phone while watching this??

I think the intended way to solve the two balls was to do it upsidedown, because the puzzle have demonstrated us the gravity with the first ball. The second did it too but not so precisious

thats such a smart solution. i would have never guessed that such a great simple puzzle

Just out of curiosity, would a magnet do the trick? Could you guide one ball bearing around with a magnet with affecting the others? To me, the trick is thinking about the materials. Aluminum and acrylic don't have the same magnetic property as steel ball bearings.

I ❤ impossible puzzle... They takes less time then the "possible" to solve them 😆😅🤣

Wow, love the machining

If you orient the box so the short edge is horizontal, the two big balls sit in opposite inclines. You can then move the small ball past one of the bigger balls using the same technique as the first part of the puzzle, then tilt the box standing lengthwise round its horizontal plane, and the two big balls will swap positions, pushing the small ball through the channel. I'm convinced that this is the intended solution.

This feels like a mario maker troll cp 1 kinda situation

Wow a Roger D puzzle!! How did you find this?

That was one of the best puzzles in a long time. Would be excited to see the other R2D2 puzzle.

My brain dies from only watching. Your patience is sth I'm jealous of.

No fair using a magnet! 😁 What a unique design. Tolerances are mind-boggling. Love the vids as always... Keep on puzzling! PS: Maybe a polarized filter would reduce some of the 'flashing' from reflections off of the shiny glass. Just a thought.

I imagine that a light tap from de bottom (the name face) while the puzzle is in same position as the first ball would work.

I like it.. its looks so aesthetic and elegant 😍

Solution for 2nd part of puzzle: you are supposed to do a fast movement forward and stop without moving back. that way the 2 big balls will go up and widen, and the small ball will move back due to the BOUNCE of the wall, the ball will reverse its direction yet the 2 big balls wills stay at the wide point, and the small ball will move pass them. The ball bounce is the twist to the puzzle (sorry for the pun).

Accelerate moving the box downwards so that two bigger balls stick to the top of the caves due to inertia, and the small ball between them rolls to the top of the horizontal tunnel. Then stop acceleration but still moving with the same speed to keep two bigger balls at the top and the small ball will bounce back. The critical part is you have to change acceleration after big balls hitting the top of their caves and before the small ball hitting the top of horizontal tunnel.

The first part is very uncanny how they meet at the same time but it keeps getting stuck, which was annoying as hell

Yes I want to see you solve the other one as well!

Excellent puzzle, please show the 2nd one too. I don't usually like dexterity type puzzles, but I like the concept behind this one, great!

Hello there my favorite RU-vid channel.

cant believe this is a 10 difficulty, its the only puzzle I got the solution within seconds.

Even I had a moment of excited disbelief when I seen the ball hit the other side channel.! That was awesome!

That's really a cool puzzle. I will be interested to see the second.
