This was super impressive, but then I thought about the fact that every single mass produced 21x21 had to be assembled 😳😳

For anyone wondering, this video was actually filmed BEFORE ever scrambling or solving the cube! So if you were worried that I messed anything up, it's actually had 10+ hours of stress testing since I put it back together. :)

other people : hesitates to scramble the 21x21 z3 cubing : let's take apart all the pieces

Even if V-cubes didn't make the best cubes, we do still owe it to them for making it possible for companies to even understand how to make such big cubes as the 21x21

The Moyu 21 is actually a 3x3 inside a 7x7 inside a 13x13 inside a 17x17 inside a 21x21 (you can pause at 9:34 to look at which shell each layer is hooked under). At 6:54 you can also clearly see which pieces belong to the internal 7x7. Moyu themselves called it a quintuple center mechanism. This means that in theory you should be able disassemble the shallowest shell (or innemost 2 layers) to play with the 4 deeper shells like a 17x17, and likewise play with only the 3 deeper shells intact like a 13x13 and so on. Those lower-layerd cubes formed by assembling an incomplete set of deeper shells would be functional as they have enough parts to hook in place, but unstable due to gaps left behind for the shallower shells to fill up. The hollow design seen on all the wings first appeared in the Meilong 12, and is later featured in the 13, 8 and 9 (which are not the same cubes as the MF 8 and 9). 2 extra points: The Moyu 21 also features an extremely scaled up version of the Aofu/Aochuang GTS's anti misalign mech. The Moyu 15 is also known to do this I suspect that the middle layer is actually smaller than the screw. This is technically an impossible design due to the screw having to pass through the center piece in order to assemble the cube. However, with some clever center cap design the designers got around this problem. The Meilong 13 features this too.

The amount of surface area inside that monster is incredible. It's a wonder that it turns at all. Thank you for this rare look into an expensive puzzle.

"This 21x21 isn't actually my cube for me to keep," FLIPPIN DISASSEMBLES IT

Dedication, once again Edit: He didn’t fully take apart the cube (which is what I was expecting), but still I would never even think about taking just one piece off.

Video Idea: Making a speedcube with the most magnets possible in it Rules: The magnets must have a purpose, so you can't just place random magnets to fill space You can't stack magnets either because that is just more random magnets The magnets don't have to help with the turning but they should still have a purpose I have an idea for a cube with 278 magnets in it but I don't know how to make a cube and I don't have the materials to build it and it would be super expensive so I can't make it. But maybe you can make a cube with more that 278 magnets.

That's awesome! Really neat way of explaining how big cubes work!

Oh wow! Great job assembling it!

It would be really funny if in the future we saw 21x21 force cubes. That's just hilarious in my mind.

Next video: “Making 21x21 force cubes!!”😅😢

Z3: I’m a take apart a 21x21 Me: *strugles on 4x4*

I never thought that something this big would get mass produced

it took me almost 2 weeks for me 2 fix my 5x5. i didnt think i could reassemble it, but i can't believe you can assemble it!

Sometimes I genuinely wonder; “Is this guy OK?”. It would surely have to take someone a massive amount of spare time and appreciation for their viewers to even consider giving them a video on taking apart a cube as gigantic as a 21×21×21. Wow.

9:17 - I'm glad you said it; it's definitely weight-saving primarily. There's probably 1/2 as much material (so half the weight) in those pieces with the holes.

If you want to take apart the 21x21 just try to corner cut, it will explode at once

Imagine if there is a broken piece…

Z3Cubing: Were gonna have a bit of an adventure Adventure to Some Torture to Others - Tsun Zhu Not Art Of War

Me over here reassembling my 9x9 thinking it's hard

I like how the very central centre prices are so small yet so big underneath

Hey dude!!! I just cracked a plastic peice of my MoYu 15x15, and i was crying sooo hard!!! But then it majically fit in and then I set my personal best on my second attempt solving it!! 3 hours and 39 minutes

I think the holes in the pieces are to reduce weight. My biggest is the mfjs 13x13, which is a nice even liter in volume, but it's more than half air. I think if it were any heavier, it would be a real chore to solve in your hands, but as it is, it's surprisingly doable.

would be kind of cool to see the 21x21 force cubes I don't know if anyone has done it or not but great video idea either way

2069: Hey guys! Today I'm gonna open up the 100×100! Without any further ado, let's begin! 2100: Hey guys! Finally I reassembled the 100×100! Yay!

You have the key to the door, never done 21 before 👍😁

me: scared to even touch my new 3x3... this guy: takes apart an entire 21x21

Just watched and liked all of his old videos and subbed all on 10 alts because he put himself through this

The things he do for his youtube channel...

Every single cuber: (Trying to solve it) Him: Let's dissemble it!

Hi you have the best of videos they really teach me how to do different stuff on the cube

Z3 cubing 2053: heys guys today we’re gonna be making force 21 by 21’s

The dedication he has to do this... I would be so scared to take this apart

Oh man I really appreciate you for this 😮😮

You should make a cube that has corners and centers stickered and edges stickerless and see how it goes.

Next episode: "Making MoYu 21x21 Force Cubes!!"

Everybody just glossed over the fact the he's been TAKING APART A 7X7 IN THE 3RD GRADE I took apart mine, it took 3 days. I'm not lying and he just dose it in class, he was 8. My gosh.

This hurts to watch! The fear of mixing up nearly 400 center pieces!

When you realise that Z3 will make 21x21 force cubes

Him over here putting a $1,500 21x21 back together when I can barely put a 2x2 back together💀💀💀

"Actually, I wonder if that has more to do with the turning, or if it's a weight-saving measure" Por que no los dos?

Great 👍 It must be so difficult to reassemble it🤯

Good video. But I wish you would’ve showed us how you put it all back together.

imagine making a force cube out of this! 😆

now we just need 21x21 force cubes

Such a cool video!!!!

You deserve more subs your the best cuber on KZfaq I have watched

Dang… imagine solving that and it pops And all the pieces go flying

My soul beating up to heaven while I stared at this thumbnail

Can't imagine actually dropping that. Also ik how to assemble and disassemble all my puzzles/cubes before I learned to solve them

I would gladly deassemble the whole thing, mix up the pieces, and then reassemble it

one part of on to the wings looks like a hallway to something mysterious

Now make 21x21 force cubes

Episode 2: Making 21x21 Force Cubes!

9:00 The holes are here to make the otherwise solid part hollow. Solid parts are much harder to cast properly than hollow ones, among other things.

Good presentation 👌👌👍👍

this was uploaded on my birthday :D

You’re a beast bro

Me realizing I'm missing a 9x9 peice after reassembling it then the cube sounds like a rattle toy

Are u kidding me, ur crazy Boi!

Still makes me sad that companies aren't making Cubic Stickered Big Cubes anymore

Now i'm waiting for the first guy to magnetize it... Only takes 480 magnets.

Nic job !

Hey Z3 cubing can you do a bandage mod of a skewb? Just bandaging 2 pieces gets VERY challenging.

You should make a 21x21 with the same colors

now imagine if he made 21*21 force cubes

Tbh bros the kind of guy to make force 21x21s lol

i cant believe you actually did this

Hope that we can see you solve this 21x21 😁😁😁 anyways nice video 😆😆😆

Everybody cubers' until Every cube in existence gets parity

Csh: 17x17 Z3: Nah… let’s skip up to the 21x21

Just commenting on a amazing lep in the Rubik’s cube history

Make me a video about all the pieces of the MoYu 21x21 plz 🥺 and where it puts in the moyu 21x 21

Probably made those holes in the pieces to manage weight and to be a little cost effective

Make some 21x21 force cubes

Big cube surgery - very informative hahaha

Now make force cubes with it.

Crazy, but very satisfiying.

feel bad for employees assembling that bad boy

This guy literally has the eternity of time

respect you god fo cubes

8:52 that is so cool

Bro u are insane(in a good way)

Next video: “Making 21x21x21 force cubes”😅

I thought the would take the whole cube out

today my friends 7x7 popped at school, like completely blew up so we spent 4 classes putting it back together

Imagine a WCA event where you have to put the cube together and solve it

Next video: 21x21 Force cubes

Do a full disassembly

3:10 where the heck did that v-cube 7 edge go like is he a magician?!?!

algorithms for calculating how many of each piece there are (x = side length in pieces) corners = 6 sides = 8(x-2) middle = 12(x-2) total = x^3 - (x-2)^2 3x3 corners = 6 sides = 8 middle = 12 total = 26 21x21 corners = 6 sides = 152 middle = 228 total = 386

Imagine TheCubicle seeing the title of the video

Now you just have to make 21 by 21 force cubes 😂

oh man I remember getting my vcube 7. I still have it and only solve it when I hate myself

Imagine a 21x21 force cube 😮

Z3cubing: borrows a cube also Z3cubing: tears it apart 😂

how are you so underrated

bruh this man is going to disassemble a 100x100
