This Trick Box is locked by an Ingeniously Clever Mechanism - The Radbox

[@Mr.Puzzle]

Was the explanation of the mechanism understandable? Do you like it as much as I do? Great one! :)

[@TheSniper9752]

Mr.Puzzle, Great trick box! Love to get one.

[@SangheiliSpecOp]

Mr.Puzzle it was perfect! I appreciate the effort you put in to print out an example for us!

[@rubinhorh]

Very ingenious mechanism!! and very nice of you to print out that explanation... easy to understand :D

[@joelbright6661]

Very easy to understand but I’m just surprised on how you figured it out?

[@DanZorny]

I like these kind of puzzles the best

[@Hangar402]

I'm addicted to puzzle videos now

[@Simon-eo4df]

I was the 100th like of this comment. Satisfying.

[@seanbain9086]

Hard same.

[@PhantomWolf-pd2qq]

Same

[@ModePrometheus]

Puzzle videos are a hell of a drug

[@damianlopez7630]

Thank You Mr Puzzle for taking the Time to print out some parts to show Us how the Puzzle Box Works. I Really Appreciate it.

[@Tolman18]

I really can't thank you enough personally for taking the time to print out the plastic pieces, don't want to ruin anything for anyone if they haven't seen the video yet, but it really was cool for you to take that time to make those pieces to show us how things worked properly and how it works when done the right way. Thank you Mr. Puzzle from your fan in Massachusetts, United States Of America! :)

[@TheNightFlower]

This is what I love about your videos, for people interested in understanding the mechanism behind the puzzle, you take the time to carefully explain it, including 3D printing models etc. Thank you. I loved this puzzle and your explanation.

[@NDPuzzles]

I loved the second part of the video! You should try to come up with your own puzzle boxes as well. Your videos really got me into puzzle box mechanisms and I'd love to explore them even further. Unfortunatelly as a normal person I won't be able to create high-quality boxes out of wood. The 3D-printed versions will work great as well though.

[@Mr.Puzzle]

I am looking forward reviewing your prototype! :)

[@NDPuzzles]

Me as well! Don't expect too much though. This is my first design and hard to compare to anything you are showing from mass-producers. Both the mechanism and the solution should be pretty easy. It is more the idea I liked :D I have still not sent the package (still missing a suitable package actually) but am trying to do so soon. I am hoping to be able to sent it at least on Saturday. Maybe even on Friday. But your puzzles really made me think. I have a lot of ideas with moc´ving parts in my mind that could create some interesting puzzle boxes. If this first one turned out good enough (for people to click on your video) I'll try to work on another box parallel to my twisty puzzle designs. The only "problem" with these puzzles is that once you know the solution, it is not a challenge for yourself anymore. So giving it to other people is the best thing a designer can do. On twisty puzzles I can easily challenge myself with my own puzzles... Well, lets just hope that the puzzle arrives in good condition at your place somewhere next week. I'm really curious to see your first impressions :D

[@Opa10]

ND Puzzles are you gong to make A 3D printable version? Let me know where you upload it

[@NDPuzzles]

No, I've not created a 3D-printable version of the puzzle shown above. I've created a different one which I'm going to send to Mr. Puzzle for a review.

[@Opa10]

ND Puzzles ok, than maybe I will give it a try

[@VaLuc10]

I started following you yesterday and it's the best thing I ever did! I'm with you Mr. Puzzle ;)

[@Mr.Puzzle]

Thanks! Welcome to my channel! :)

[@unclvinny]

This is one of my favorite of the puzzles you've shown over the years. I really appreciate you making the printed demo, too, I think I would have had a hard time understanding it w/o that.

[@menegaux]

Such a satisfying video... loved the 3D printed demonstration!

[@nathanokun8801]

Interestingly enough, this tilt mechanism was used in some US Army and Navy armor-piercing projectile base fuzes developed prior to WWI (and still used in some projectiles during WWII) as a major safety feature. The mechanism was developed and manufactured by or under license to a Mr. Semple and thus these fuzes were called "Semple" Base Detonating Fuzes (BDF). The rotating portion pivoting on a large cylinder looked like a closed fist with a single long index finger pointing out from it that had the firing pin at the tip of the finger. When the projectile was not yet fired, a spring-loaded pin held the fist cocked off at an angle to the projectile centerline so its finger could not go into the small hole in the centerline just above it where the primer/detonator was located. Upon the gun firing, the acceleration and spin of the shell pulled out the locking pins (there and further up the fuze between the primer/detonator and the delay element (if used) and the booster charge that set off the main explosive charge of the shell), allowing the fist to pivot and the spinning off-center weight pulled the finger to align with the projectile centerline and the fist was now free to move forward into the hole with the primer/detonator, held away from it only by a small spring. On impact with a target, the fist and finger would be thrown forward as the projectile suddenly slowed down and this set off the primer/detonator so the shell would now explode. Later, post-WWI AP shells emphasized highly oblique impact function (sloped armor on tanks and hitting ship decks at long range) and this design was not that good if the shell was rotated at the wrong angle about the shell centerline when it hit the target, pushing the finger sideways and stopping it from working. Other, more impact-angle-free fuze designs replaced the Semple design in many cases during the 1930s because of this flaw.

[@PaulTheSkeptic]

It is cool. And taking the extra time to print out the pieces as a 3 dimensional example was very thoughtful of you.

[@stellatedhexahedron6985]

I have to admit, I don't appreciate these sorts of hidden mechanism puzzles for their value as _puzzles_ -- it might be my lack of experience with them, but it seems to me that the space of possible solutions is too large to be interesting to explore. However, I can _very much_ appreciate hidden mechanism puzzles for their value as _mechanisms_ -- a very simple and lovely way to achieve this effect!

[@herbert9890]

I have built the box and it works absolutely without problems as seen in the video. Ingenious and simple function and can be reproduced with little effort. Thank you for showing me.

[@giovanniyorke7455]

I have learned when my mathematics teacher told problem solving and algebra is easy to expect the opposite, when my physics teacher told me his course is easy to expect the opposite, so when you tell me this puzzle is 3 out of 5, I take it to mean 6 out of 5

[@Mr.Puzzle]

:D

[@nyer]

You arent paying attention then, since 6/5 is just simply impossible... Also im not picking on you / anything, take what a said w/ a bit of sarcasm

[@IronicHavoc]

NyanimeGamer I mean it's not mathematically impossible, unless we're talking about probability or something else that's normalized. It's just not within the established conventions of a rating system.

[@nyer]

The guy literally just said "6 OUT of 5" you are taking 6 out of 5 or are putting six on 5 and of course its not within the established conventions of a rating system since thats just wrong and sites like IGN, yelp, and such has a (arguably) correct and plausible rating system, and IF it isnt then it is still mathematically impossible, its not "rating system impossible" its still mathematically impossible ( too many mathematically's and impossible's )

[@IronicHavoc]

NyanimeGamer You chose to represent it as 6/5. Which isn't mathematically impossible. You can absolutely have greater than 100% in mathematics, you just exceed one whole unit of something, or have a ratio greater than 1. Now on the other hand, as you just mentioned, saying something is "6 out of 5", or as what Mr Puzzle would specify even further as "6 out of a maximum of five" is logically impossible. Which would make sense practically, since without a hard maximum you can end up with arbitrary ratings, which is WHY it's not reasonable rating convention. I wasn't disputing that. But ultimately the decision to set 1(100%) as a hard maximum isn't inherent to mathematics, it's a practical choice. So practical in fact, that if somebody defies that hard maximum to say "6 out of 5", it's clearly hyperbole and doesn't bare pointing out. In addition, if someone were to correct this hyperbole, then obviously they were doing so on the basis of the aforementioned "out of" logic. But if they happened to use a numerical representation that doesn't explicitly convey that, that gives me a chance to be a stickler semantically and ignore the obvious intent of what they'd written to sound like a know it all.

[@BarbaraMerryGeng]

I find your after/ demo on the solution to be quite impressive !

[@kirtishastri275]

Wow the printed solution blew my mind You are truly a genius Amazing

[@Mr.Puzzle]

The genius is how developed this! :) I only printed the sample to demonstrate it. :P

[@snidelywhiplash8399]

I like the fact you printed some parts to explain the solution! It really is a cleverly designed puzzle!

[@ricardomendez7803]

That was brilliant - thanks for clever explanation too.

[@Jay-qs2oi]

The explanation was a great touch! Nice that you took the extra time to print the pieces and demonstrate it. Great video as always!

[@Mr.Puzzle]

I am very happy about all that positive feedback of the explanation, thanks!

[@fatmn]

Great job with printing the mechanism and showing us the inside. It really took your video to the next level! Well done!

[@Mr.Puzzle]

👍🏼

[@bannor99]

Great demonstration of how it works!

[@JPT315]

Maybe my favourite video so far Mr Puzzle. Learning how a puzzle works is just as enjoyable as solving it

[@Mr.Puzzle]

Glad to hear that, thanks!

[@cavemann_]

Dunno m8, I could listen to him even if he was ranting about some boring stuff xD Good voice

[@360.Tapestry]

very clever design and very cool that you can 3D print pieces to demonstrate the inner workings

[@13vatra]

Wow! This solution is amazing, and your explanation is perfect.

[@JDNboy12]

I totally thought this was some Canadian puzzle... Why the giant maple leaf on the front?

[@adamp8761]

Willaby Zarkute to leave you puzzled :D

[@EmergencyChannel]

It’s a Canadian weed stash box

[@TIMEtoRIDE900]

It's not big enough for that !!

[@CaveyMoth]

You can store maple syrup in there

[@Eeda01]

The wood is maple, I guess.

[@Ripmav]

Super Idee mit den Plastikteilen!

[@Mr.Puzzle]

Danke!

[@tiki_trash]

I am imagining multiple wheel and or pawl and ratchet mechanisms for even more steps to solve the puzzle. Thank you, mind blown.

[@paneofrealitychannel8204]

Super. Very cool.

[@arpstatistics7764]

Your explanation of mechanism is quite understandable... Its very tricky...

[@RoyNellen-v9f]

loved it, gonna design it for 3d printing and geocaching..

[@chaddles623]

I really appreciate the 3D printed demo after the sold showing how it works, very cool and adds alot to the video. But what does the metal pin do that slides in and out?

[@lsdave42]

"Later, when we look at the solution, we will do." 10/10, subscribing

[@balnarayana]

very good and intelligent puzzle /congratulations

[@jacklarson6281]

thanks for explaining the mechanism. ive just discovered your channel along with some other puzzlers.. its given me a bunch of ideas and i want to take a crack at making some puzzles and puzzle boxes

[@davidmedford1166]

I can't get enough of watching puzzle boxes. They are just so creative and cool.

[@Camps2630]

Even your easiest puzzle would take me weeks...yes, even that giraffe one 😉

[@karlriley1314]

Really a great puzzle Mr. PUZZLE.

[@arunfernandez1999]

It great i love it make more videos on how to puzzle works. great job

[@donfaustino2010]

Subscribed just a few hours ago and already I’ve viewed through almost a year of your content. Your passion for these things really comes through. Keep it up :)

[@shtsandgggles6865]

The best 2nd part of this video is the best dude, you always answer questions that everyone is asking in their own heads, top bloke you and also very intelligent, I feel I'm more smarter just from watching all your vids man, please don't ever stop making content, your hard work is appreciated dude

[@Isla_Auarita]

This is the perfect D4/D5 Geocaching container! Brilliant!

[@zoso9896]

Thank you for going to effort of 3D printing to explain the mechanism. Thank you.

[@Mr.Puzzle]

Welcome!

[@disgruntled181]

This is the first time I actually stopped the video at the spoiler break to buy a puzzle!

[@Mr.Puzzle]

That's why they are in, enjoy!

[@mahamadbakhitHamdok]

You are smart. I'm sold to this content.

[@Name-js5uq]

What a great solution, and thanks that demonstration.

[@medicalmanport1136]

I spend hours!!!! a day watching your videos first I've seen with the 3D print out and loved it

[@Mr.Puzzle]

Thanks!

[@abundantlifepathway4181]

Thank You. Very cool! You inspired me to make some for my granddaughters. What kid doesn't love a trick box with a "secret" solution.

[@Daynaleo1]

Your explanation was excellent. Great job.

[@mhmdkhairy4423]

I LOVE WHEN HE SAYS " MR PAZZULL " 😄

[@Oferb553]

Simple and nice!

[@chandersital513]

Very nice video thank you very much

[@jbagandalf1]

Very cool. Thanks mr. Puzzle!

[@philtanics1082]

Mr Puzzle you are a certified maniac. Much love.

[@MrV2u]

Boss level puzzle solver. Love your video and the awesome demonstration of the mechanism.

[@Mr.Puzzle]

Thanks!

[@CaskStrength777]

I love it! My favorite day hands on was a visit to Izumiya on Christmas day in 2005 in Moto Hakone, Japan. The owner showed me all kinds of karakuri boxes with gravity & magnet and other tricks that opened like this- so cool to find a channel covering these. I want to make some out of metal for years now as a machinist 😁

[@crooz13]

You Are Genius Ty 4 sharing

[@nativesun7661]

Wow, talk about going above and beyond! Great job dude. Best use of an actual 3D printer in an explanatory video about solving puzzles! Kudos.

[@yesnobabu]

Excellent design

[@erfut]

Great Man, Thanks

[@tinepone]

great representation of the mechanism!! love these videos

[@marcelvdberg]

A crystal clear explanation!

[@buggsy5]

Cute and simple "pendulum" style mechanism. Nice for a puzzle, but the actual lock security is next to zero. A thin probe or shim will bypass the lock in seconds. Keep up the good work.

[@aliaslmx]

Awesome! Simple and clever!

[@TacoDemon210]

Fantastic explanation.

[@crystalheart9]

Very fun puzzle and a beautiful wood box. It's so pretty I would want to keep it out where it can be seen. Do you keep any of your pretty looking puzzles on display?

[@Mr.Puzzle]

Currently they are all in a shelf but completely messed up. This will be changed soon.

[@crystalheart9]

I would probably have the pretty ones on display and if I had a lot change them out now and again. Love your videos :)

[@Gurbo8]

I always like puzzles which have easy solutions when you understand the mechanism, but are tricky when you can't see them. This puzzle box is a great example of that!

[@Mr.Puzzle]

absolutely

[@grzegorzbrzeczyszczykiewic897]

im impressed how fast ur channel grown up im watching ur vids sice i think 8k subs an i love it keep up the great job man

[@Mr.Puzzle]

Wow that's amazing! Unfortunately, it's not possible to see the subscriber rank in youtube.

[@planchetflaw]

Very well explained at the end. I love your attention to detail.

[@tyn999]

Very smart mechanism and your explanation was awesome!

[@metametodo]

I also loved the mechanism a lot, it's awesomely creative. I'm not very well now, especially mentally, I wasn't going to comment, but this is so awesome that I had to. I also decided to comment that I really love your work, and I agree with some main comments here. I'd be very happy if you showed your collection in general, or talked about some technicalities, your favourite kind of puzzle, your thoughts and maybe small proto ideas on things like your own puzzle designs, I don't know. I say this with all the due respect, I definitely respect your privacy and preferences in case you disagree. Thank you.

[@SBVCP]

I absolutely LOVE it! You should do a video about your favourite mechanics!

[@Mr.Puzzle]

Interesting idea!

[@ravenlord4]

Are you an engineer? I love the approach you take to solving and explaining the puzzles.

[@Mr.Puzzle]

Yes

[@Tolman18]

Wow you nailed his profession! hahaha... Great job Raven Lord. :)

[@rayfinkle9369]

[@Mr.Puzzle]

Glad to hear that, thanks!

[@mattjohnston2]

That's a brilliant puzzle, and your demontration of how it works was just as brilliant!

[@Adamharvey5]

Nice video, great explanation of the mechanism. Look forward to seeing some more.

[@gokhanunsal542]

Good explanation man!

[@lincolnthinking]

simplicity in design transform into a fiddling complexity, very nice ~

[@hemandestroyall]

Because this video I purchased one. Beautiful.

[@Mr.Puzzle]

👌

[@hyperreed]

Great explanation. Did you disassemble the box to figure it out or did you just figure it out using your amazing mechanical skills?

[@Mr.Puzzle]

Disassembled the box.

[@mermaidheather]

It took me a while to figure this box out. Watched your video but it didn't help as much as I thought it would. Turned out that the box I have, I had to turn it to the right first and then to the left to open it. I was very happy once I did get it open. Thanks for doing these videos, very entertaining even if I don't get the puzzle.

[@Mr.Puzzle]

The disks are probably assembled in opposite orientation on your sample.

[@xpndblhero5170]

Sweet mechanism.....

[@annaruyer4681]

nice box, it looks great and smart build.

[@otakuribo]

that explanation was _amazing_

[@joshgrimm8443]

I put this mechanism in a box that i made after seeing this. Love these puzzle boxes.

[@Slimd613]

This is the box version of the NEWS Hanayama puzzle. I love this puzzle...

[@vacuumelite2065]

Every time I watch your videos I feel better. That is a priceless gift Mr Puzzle. :-)

It is ASMR!!! I Also Feel a Deep Sense of Peace and Safety and Calm. I'm Also Sharing the Videos with my Wife...as She can also benefit from the Soothing Calming Effect...Lol. Thank You Mr Puzzle.

[@TerryHesticles280]

Do you stream or make videos of you actually sitting down and figuring these out ? I think it would be great fun seeing you go through the puzzles and using what you know to solve them. I know you kind of do that In these videos, and i enjoy these videos, but like some other channels out there, it is fun watching the whole process as well!

[@Mr.Puzzle]

There is only one am afraid. kzbin.info/www/bejne/Y4LTnaGchZ5madk
