This is absolutely INCREDIBLE!! Our jaws are on the floor here at K'NEX HQ. Bravo!!

This is a video of my childhood. Good to have saw it again!

Some of these mechanisms really had me in awe. I've been designing all kinds of mechanisms for over 20 years (just for fun, I like to design and build stuff, none of it is online unfortunately), and this really gives me some stuff to think about. The way you approach basic mechanical properties inspires me sir!

Hey Shadowman. Been a ball factory enthusiast since I was 8 and can't believe there are so many people still dedicated to the machine. This is really the most epic build I've ever seen. There are others that are bigger and take up larger spaces, but the sheer density of what you've done in a single tower is really impressive. The mechanics are unprecedented. Motions are very smooth, gravity is used in almost all downward motions, and most of the mechanisms (or elements) seem totally original. The ball raising mechanisms are similarly smooth. It looks like you have a very, very low rate of 'unintended drops' which is impressive with so much complexity. The gimbal really stands out to me. The aesthetics are amazing. Sometimes with so many parts you don't see as much attention to detail, color-coding, etc. but that was clearly a major consideration here. There doesn't appear to be much non-Knex pieces at work here either. Your use of non-perpendicular angles on some of the gravity arms is impressive and I think I saw some 3 and 4-bar links in there which are very difficult to get right. What was the hardest element to perfect? Also, nice job on video editing.

This... actually brought me to tears several times. I can't believe I'm only finding this machine until just now! please never EVER stop what you're doing. Don't let this absolutely amazing talent go to waste!

As a designer who had worked at Knex, I salute you.

My kids received a roller coaster set for Christmas. We built that, and after having some fun with that, we watched this video, and now they (and me) want more K-nex lol.........This build is ridiculous! My two boys keep saying "How do they do that!?" HAHA, man, this is epic. Such an incredible job dude! SUBSCRIBED!

This belongs in a museum

In-sane. Just insane. 3,5 years, yeah I am not surprised. All the structure is just sweating intelligence, physics knowledge n creativity. Thumbs up.

WOW!!! I've been fascinated with Rube Goldberg's and rolling ball sculptures since childhood. I started out by using marbles, cardboard chutes, paper towel tubes and paper cups with holes cut in the bottom, supported by tinker toy structures and when I got older and had more money, I'd buy Spacewarp kits and all kinds of odds and ends, like plastic funnels, plastic marble chutes and employ these pieces in more elaborate contraptions. I guess this is a peculiar form of insanity that possesses some of us...lol. This is the most ingenious rolling ball sculpture I've ever seen! I am just in awe! Thanks for sharing.

Big Ball Factory, the heart of this machine

this is the single most greatest knex creation I have ever seen. the amount of engineering and planing that went into each path and element is astounding. many parts were like the movements of a clock. others were just simply engineering amazement.

Wow, was just watching this over a fresh pot of morning coffee, and got so pumped I shed a few tears! If you were a gangster, you would be the Godfather! Amazing model and video. Thanks for sharing.

If you aren't the creator of Knex, you are making him/her very proud right now.

This is one of the most satisfying videos on youtube.

It gives me nightmares just to think about the hell that must've been designing and building this thing. This is amazing; nothing else like it. You really deserve more attention.

This is flat out, the best knex ball machine I have ever seen, very creative ideas and engineering man

wow you are the true ball machine master of old wisdom returned to show us all how it's done

Unbelievable! This has to be the best great ball machine I have ever seen.

I'm speechless... Man, you are a hero. This is insane.

Your level of creativity and ingenuity is just incredible O_O that is nothing more than a masterpiece built by a genius .... just WOW. If you're not a top mechanical engineer to make a living then your talents truly have been wasted and the world would be at a loss. It would be a cardinal sin to ever take it down, like destroying the Mona Lisa. Bravo Sir, much respect!

I'm impressed with how many of these mechanisms are just clever use of counterweights. Some of those fancy arms swinging around I had to look at multiple times just because they were so elegant.

As a fellow builder of massive K'nex ball machines (see my profile pic :P), this is one of the few I've seen that truly floored me. Not only is this thing bigger than anything I've dreamed of making, it's also extraordinarily compact. It looks like very little space is wasted (there is slight room for improvement of course, though all I can see is that the return chute is awkwardly large). I would estimate this as taking at least 50,000 K'nex pieces, quite possibly a lot more. There are just so many finely tuned mechanical components, it's staggering. I get headaches just trying to balance a single-arm device so that it's triggered by the ball landing on it; you seem to have mastered the art of maximizing response without even resorting to adding extra pieces that make everything look bulky. I love the tracks where the ball cruises on through if it's still moving, but falls off if it slows down - I could never get something like that to work. The track selectors you have are also really slick, I've never really considered making one that selected more than two tracks. Some things in this model are elements and mechanisms that I could never have dreamed of: namely, everything that doesn't fall in a straight line. The two-arm lever was especially impressive: in order to swing, it completes a full rotation about its axis. I can't even understand how that works... Even though it's just building toys, this is a real feat of engineering and you should be proud of what you've made.

Used to love my Knex as a kid back in the 90s, was quite limited and seems alot more pieces have come out but used to make guns with them that actually fired and hurt lol, also made a safe with a key that was so strong you could stand on it without breaking, and a bunch of other things, loved it so much then grew up :( now as an adult im so tempted to go grab a few sets and learn again

I just been cleaning out the shed.. Come across boxes & boxes of the stuff.. Good memories with the children back in the day..

this is amazing, i just cant even imagine how you could come up with some of these ideas. i mean sometimes when i see rolling ball machines or rube goldbergs ill see like 2 or 3 novel ideas, but theres at least like 10, 15 things in here i havent ever, ever seen. amazing dude. really.

You are the kind of person who makes my usually monotonous day amazing. Thank you.

This made my fingers hurt just thinking back to playing with Knex as a kid when I'd play with them until my fingers couldn't snap the pieces together anymore. Fantastic job!

This may be the best Knex ball machine I have ever seen. This motivates me to finish my most recent one.

I don't know why but I couldn't stop watching

I don't know how I got here, but this is super cool.

You are a builder I look up to. This machine is incredible

Ingenious lifts, original path seperators, creative and new elements! Kyle, I have been waiting for this machine for over 3 years but I never expected you to pull this off! This is by far the best ball machine on youtube, keep up the good work!

I've tried so many ball machines by other people to make my own, but it didn't work. Until I saw yours, I started making good ones that take up half of my room. Thanks for the help

I can't even put together a cheap marble set with more than a couple of paths that work great. This is straight engineering magic to me.

Man this is by far the coolest thing I have ever seen done with K'nex. You absolutely blew my mind. Fantastic engineering, excellent use of space, phenomenal ingenuity, and outstanding design elements all combined into one mind blowing masterpiece. My only wish would have been to help you in the process. Kudo's man. I am so jealous of your abilities.

If all Borg cubes were like this, I’d happily be assimilated. Seriously, this is pure joy to me. Thank you.

The degree of ingenuity and patience it must have taken to build this is unimaginable.

Legend says that the Citadel is still standing to this day. Seriously it would heart breaking to disassemble this piece of art.

I couldn't take my eyes off of this. I will share with my son later today.

"NOW you're thinking with portals!!" Also, poor little Knex man that was caught in the nuts by a ball!! LOL This whole video had me watching it the entire time mouth open in continuous surprise!! It was such a ride... I've felt the excitement of a kid on Christmas! Thank you so much for this, I'll never forget how beautiful it is :)

I used to make things all the time when I was a kid. Some of the older larger scaled things, customize and expand on until one day my house flooded and I lost them all. Never did replace them but seeing this, I really wish I had them again. Great stuff man.

I don't have the patience to build such an impressive thing. props to you, my good sir.

This thing belongs in a museum!

I'm extremely impressed by this. This looks like it took a lot of work to design and construct, and the fact that it's mostly if not entirely mechanical is absolutely astounding. Great work!

Everything is so precise, working wonderfully with gravity. It's mesmerising.

Oh god! Human mind is so amazing....All the creativity and meticulousness that goes into making this.....Hats off.

Thanks for the comments everyone, for those of you who want to see the video without music, I uploaded it here: kzfaq.info/get/bejne/q6tlhdx02tvTc6s.html Thanks again for your support!

This is incredible! The paths, appearance, elements, and lifts are incredible. Love this build! That's all I can say. I'm still overwhelmed! Keep up the good work! :D

I don't care how old I am. Shrink me so I can kick off my shoes and play in this play place of awesomeness so awesome it would make Discovery Zone cry.

Oh wow Knex. I remember one time when I was like 8, at a shopping center there was like a Knex promotion going on near the food court. They had a bunch of tables for kids with buckets and buckets of Knex pieces and if you constructed the model they displayed then you could keep it. Like an all you can eat buffet but for making Knex. I must have made like 40 of the damn things, I remember my Mum was getting embarrassed like "ok enough now hehe."

11:30 This is a triumph. I'm making a note here, huge success.

This is insanely good. The best ball machine of any kind I've seen in some time. Ridiculously creative.

There's something really soothing to watching the balls go down their tracks with that music playing. Nice portal reference on track 15, by the way. I can only imagine what you would come up with if you were to design a platformer video game.

Absolutely Amazing! i JUST love all the "do-flickies" that are activated with the weight of the ball. Unreal!!!!

This might be the first sensible and interesting video Dan has ever brought to us

It's very cute, that the balls are in some ways connected with each other. Great work!

I am blown away... Excellent work!

I can't even describe how amazing this is. the functionality is amazing, but beyond that every bit of OCD in me is so pleased at just the pure beauty of this enormous contraption. this is amazing in so many ways!

This is incredible. Very nostalgic for me. I had a huge chest of knex 20 year ago with the big ball factory and I recognize every piece.

This is unreal. Thanks so much for posting this.

3 years ??? Wow , you did a fantastic job !

Why would 26 people dislike this???!!! This is amazing congrats dude! Wish I had so many pieces.

ENGINEERING AT ITS FINEST AND MOST SIMPLE FORM #LOOOVVVVEIT

Wow, what an inspiration, what a lot of new elements. Will use some in my Andromeda ball machine.

This thing is a work a pure mechanical art and genius. It's absolutely beautiful and needs to be in a museum or something, or displayed at the knex headquarters.

Some of the machines on here are absolutely brilliant. Mind blowing!

this needs WAY MORE VIEWS!!!!

Holy shitballs!! 3 years!? That is incredible and insane all at the same time! That's awesome!!!

Amazing! My 2 year old daughter loves watching this too.

So much creativity, you've done things with Knex I'd never imagined possible! Thank you for sharing it with us!

Everyone else here is saying how awesome this is, and I'm just thinking about how awesome it would be as a theme park ride. Seriously, why aren't giant gyrosphere machines a thing yet? Get on it, engineers! =D

i respect the dedication to your craft. well done

This is crazy. You are the genius. Good job man.

its so cool how you have used all the knex wheels as counterweights for most of this

Path 17 definitely my favorite

I didn't search for this and neither did you but we sure watched it all.

This was in my recommended... I was not disappointed at all!

So insane. I can't even fathom making all of that work together without any interference.

Delightful. The path switcher is ingenious.

Mind blowing... beyond genius.

Thanks for posting this. Brings back wonderful memories of me and my son's playing with them, obviously on a much smaller scale. Don't understand why anyone would give this a thumbs down. Love the music also!

Yes sir! This is one of my favorite machines of all time! So many new elements, the video is done so well, everything is just great. The attention to details in the machine is insane, I love the little gimmicks here and there spread out through the machine. The portal style track at 11:35 really sketched me out for a minute haha. Anyhow, I'm glad that you got back into building and were able to finish this wonderful machine, hopefully you'll keep at it and the next projects will (with great difficulty) outdo this one!

Best I've ever seen. May not be the largest but it's the most creative and well designed. Also I loved the portal shout out

One of the best ball machines I've ever seen! The elements are really creative. I only wish it weren't so dense so I could see it better.

kontemplating this marvelous contraptions, gave me a batter understanding of the universe.

Now this is one super ball machine! The background music also fits super-well, I love it!

Epic build, thank you for sharing this!

Potential energy dissipater, MASTER. Hardly any powered arm's there, and mostly all good balancing and precision. i absolutely love it. all the best from the uk.

wow so awesome. something about watching the track and the music made it very calming to watch.

Wow omg 😳🤩😍 I really liked path 8,12,13,14,16, and 17

It's 2020 and this just fell into my recommended feed now 🤯🤯

I just finished watching this video, and all I can say is that's one of the most fascinating ball machines ever!!!

Incredible! Well Done! Awesome Engineering Beautiful Design LOVE IT!

i love all the new elements

This is superbly cool. I really like all the elements with the double pendulums and the stuff that twists or rotates as the balls go through.

THIS IS INSANELY WONDERFUL!!!!!

Love the portal reference on path 15

I just wanna say, the timing alone on the portal ball is superduper impressive, taking nothing away from the rest of the citadel. :D

Wow 3 years amazing
