TAKING APART the MoYu 21x21!

While I had my hands on the new MoYu 21x21, I decided to carefully take out as many different pieces as possible. Watch me explore the mechanism and tell you about how it works!

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. :)

[Kewbix]

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

[J.Galib]

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 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.

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.

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.

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.

[enderdude]

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

[theatrobert]

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.

[AwesmeBadger]

This IS the unboxing. Your undoing the box.

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

[PedroCubing]

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!

[DVSS]

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

[KanarisTM]

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.

[lutimstrickshots]

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

[hriditscricketshorts]

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

Video idea: making the worlds largest force cubes

[mortimermouse]

I never thought that something this big would get mass produced
