TAKING APART the MoYu 21x21!

[@Z3Cubing]

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. :)

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.

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.

[@dadnbud]

Had to comment. I'm now middle aged. Been puzzling since the 80s! So been around the block and may know a thing or to. Lol. Rubik for years stated it's impossible to make his design larger than a 3x3! This was true for so so many years. 4x4 and 5x5 which was called the professor cube. They were horrible with turning and snagging. Not made for speed solving. Then a man called Verdes from Greece changed it all! V-cube! This revolutionized the sizes and mechanisms.Verdes owned the guts(inner mechanism). He didn't play with all the chinese knockoffs or the companies like the cubicle. This was years ago. This also led to the largest knock off of puzzles...like ever. Worse is the respected manufacturers today of these large 21x21 made it big in business due to first making knock off puzzles. Sheng, yuxin, etc were kings off knock off puzzles. Verdes sued and didn't put up with the knock off companies. So all these now respected puzzle manufacturers were once knock off artists! Weird how they were thieves and now considered the best. Funny how this worked out. Mf8 also stole many puzzles and ideas! These are all now top manufacturers! Even the Cubicle back in the day had cease and assist letters for selling knock off puzzles! Nobody knows, cares, or remembers this. However Sheng, yuxin...they stole all ideas then transformed the guts of the puzzle so Verdes couldn't touch them legally anymore. Gotta hand it to these manufacturers. They made so much money illegally and so did cubicle website. The dust settled and now the once knockoff kings and knock off sellers got away with it so much that now they are now considered top makers and sellers. We once refused to buy from them and many sites were shut down due to legal issues! I see they all sell well still and people forgot. Cubicle still around and nobody the wiser. These large cubes were once stolen off v-cube, to then they remodeled the knockoffs to be different and become their own. Now they sell better then v-cubes and so much cheaper. V-cubes were left in the dust. Vcube finally made 8x8 when 13-15-17 size cubes were being made. I bought an 11x11 from China on release day years ago. Unbeknownst at the time the sellers site was shut down due to selling knockoffs! I paid $200 and later owner gave me $50 refund for delays. Open my 11x11 and its 100% modeled after the vcube! Illegal knockoff. I had no idea of these issues back then. Time, trials and tribulations. Now its just a story. Gotta hand it to them though. They actually stopped copying Verdes, made their own inner designs, and now are top well respected puzzle manufacturers!

one thing i do not understand is when you are solving it how do you solve the plus centers and the x centers in to the right spots? i thought you just need to get the whites to the right side i did not know they each had only one spot they could go.

That's essentially what makes it so time consuming. You have to do everything one piece at a time, looking all around the cube for the exact center you want.
