By the way, the largest possible shadow is shaped like a regular hexagon but the shadow in my animation is kind of irregular. My bad.
UPDATE:
some people are not so sure if this would be possible in real world, because there are some parts of the cube clipping through another one. However that is just an error I made while animating the movements of the cube, in reality there is enough space to even fit a slightly larger cube through. You can see the math and history behind it here: en.wikipedia.org/wiki/Prince_Rupert%27s_cube
Hope this clears things up
Think Twice close enough bro
A. Valentine hmm im not sure, it was probably just my error in animating because I set up that scene by hand so the placement was not perfect.
Think three times for this one then kkkkkk
You're a genius!
๖ۣۜLǝgiƬkɨłłzᎵrσ『ђeяø』 If not just by the mathematics, he is for the animations.
My engineering professor on day 1 asked us this. We all said of course it was impossible. The he shows us this example using two wooden blocks and said "dont be afraid to think unconventionally, you'll never have a revolution doing the same thing that's always been done"
That professor? Albert Einstein.
don't*
@@HandledToaster2 yeah as if only einstein has the right to be intelligent.
Then You Are Lucky
Probably the problem with how both he and this video pose the question. Asking it in a certain way can immediately imply a lot of restrictions. For example, the first hole cut in this video implied the cut can only be made in to one face and out the opposite face, not though all 6 faces as the final solution showed.
Very interesting concept. I feel slightly annoyed that at the beginning it was asking if the light cube could fit through the dark cube but at the end it put the dark cube through the light cube lol
same here
sAme
3 times 6 is 10 For the sake of my faith in humanity, I hope you’re joking. Haha
Angery
same
This makes more sense than the video showing a sphere that can turn inside out.
lol
Just An Edit ikr
You mean it's a lot simpler and easier to understand
Because you can pinch this one here infinitely tight. Makes shit a lot easier...
Because this one actually makes sense and is not dpendant on impossible physics
If I were the white cube, I would feel very violated. Having such a large hole bored into you, that huge chunk of yourself taken away, and then another guy comes and fits themself right in there.
Eurgh.
Billy Ma-gusta life is life
Nah, the other cube was just a copy of itself
God that is..... Wow

I've never heard of Rupert's Cube so I had no idea where you were going. When you compared shadows, I still didn't think it was possible. And Voilà! It worked. Nicely done.
I didn't think it was possible when I first heard the problem as well
Rupert was like: "Forget thinking outside the box, I'm thinking right through it !"
Good one!
LoL
underrated comment
I am now woke.
That is one sexy jiggly puff...😂
*Real shit?*
Make the whole cube a hole so the other passes right through easy
:DDD
Pretty straight forward and simple lol
It still wouldn't fit though. Since they're identical, the edges would be aligned and a hold of the same dimensions would just stop it there.
Smort
When you first presented the question I was like 'wtf absolutely no way', then as soon as the cubes started rotating at 0:37 and I was looking down at the point of the cube, the solution came to me. Very neat trick!
What a tragic story about a kindred spirit who just wanted to fit in but needs to mutilate themself to do so. Sosad. Icryevrytim.
And that, son, is where octahedra come from.

Yes I was right.
At first I have no idea. Then I remembered a problem which is: how can a person pass through a small piece of paper. The solution is cut it a specific way so The it makes a large hole.
Great thinking, well done
Roman Neill Basically, cut out a shape with a very large perimeter (e.g. a very spiky star with lots of points), then cut out the interior of that shape, leaving just a thin outline. Then you can stretch that outline apart as far as the perimeter will allow you, and step through it.
Red Salmon Holy crap, I remember that from elementary school aaaaaaaaa!
Roman Neill
Because that piece of paper is significantly smaller than a person, cutting it in a “normal” way will never get you through the hole
Red Salmon i figured it out but how does your “solution” explain anything lol
*gray cube has obtained silver armor*
lol
Isn't That Like Wearing The Skin Of Your Enemies?

Ty Johnson Why Are You Typing Like This?
Congrats! Must have been a pain in the ass to compute that geometric intersection! ^_^
Patrick Apom 2 mins of CAD editing and voila that geometry is done and exported into an animation programm
0:19 - gone sexual
this is actually so simple but so ingenious
Oh, science and math, you never cease to amaze me.

Nice choice of music! I knew I recognized it from somewhere...
Herobrine . thanks, took me a while to find it..

Me:uhh
My math brain: it's on to you topology.
My topology brain: uhh, uhh
My topology brain:WAIT A MINUTE!
My Topology brain: If I cut a cube when it's on its left edge then I get a bit of cube on the left and right! So therefore I need to cut the cube at an angle where the left and top edges are fully visible witch means that I need to cut it from the corner!
My Math brain:(That Explanation took 5 years)
My Math brain:I need to cut it from the corner!
My common sense brain: you could have looked at the shadows...
My Math and topology brains:Oh...
Me:Why did I take that long?
Pro Odermonicon rip to your brain
@@randomguy-mx3dn which one?
I was going to skip a lot of this video, but the music stopped me from doing so.
Thanks.
It's just 2 mins tho...
Instead of making the white cube 'smaller',you removed a huge chunk from it so the grey block can pass through it. Genius
/s
Math is beautiful...
One day I will make a metal version of this, "a very cool toy". Although I will probably need three cubes and special tooling to make it. Cutting that hole in a cube is not easy task and having the hole filled is what makes all the fun if this is going to be a toy.
Oh thats think outside of the box for sure. No one expect to cut a hole from angle. Good work btw
thank you:)
So great! I love all of these!
Kyle Burke thank you!

underrated channel, by a lot, these videos are so calm and relaxing while also being intriguing and thought provoking, you're channel is amazing
Thank you Think Twice, very cool!
thats clever, a bit of logical thinking mixed with math, amazing
I guess that makes sense... but wouldn’t parts of the white cube essentially need to be infinitely thin to allow this? That means to have this in the real world you would ether need to make the white cube an undetectable amount larger than the other cube, or have it bulge at those points, otherwise the cube would be cut apart before the other cube would be able to fit through it...
Indeed, and if we are allowing infinitely thin sections of the outer cube then you can just cut straight through the centre as is shown at the beginning. If you actually do the maths it's not even going through the cube as it occupies the same space so the whole video is really a lie.
No, there is actually a bit of wiggle room that's kind of hard to see. You could actually cut a hole to fit a cube that is 6% larger and it will still remain one piece.
You all are assuming that the width of the rotated white cube is exactly 1, smh.
Miles L. is right, this isn't a prefect cut.
Jeremy Shuler If it can be done with a real cube, surely that would be more convincing
Andy Wright ruclips.net/video/e3-Ta9DF4Cg/видео.html that wasnt too hard was it lol
Job interviewer: so what can you do?
Me:
Better love story than Twilight.
The animation moves like surreal entertainment
This reminds me of the times I would draw a cube in class because I was bored. Then blinking repeatedly until the cube seemed to move.
Excellent choice of music. I love that ost.
now, that's science!
That Death Parade music though. Good choice.
*when turning a sphere inside out isn't enough*
My mind is blown. Thank you!
Thank you for reminding and showing me to think outside the box.
THAT IS GENIUS
When you spawn 2 cubes in Gmod but you spawned them too fast so now they're clipping into each other
I don't know how, but one day, I will use this knowledge.
Amazing and elegant
I kinda felt like I wanted to give a standing ovation at the end lol! Never had a video that did that to me before. Maybe it was the music?
Perfection.
11PM: just one more video before bed

How to give your cubes a cute outfit
im looping this and good night!!
This is art.
This is like a geometry teacher's dad joke.
00:15 YES ! turn the cube so a corner is facing you and the outline is a perfect hexagon
Now cut a square hole into it
that's it
That was mind blowing
I didn’t even know this was a question you could ask. Genius is more asking the right questions than it is solving them.
Some earrape Harry Potter music would be fitting
This new cube fetish seems pretty cool
at the opening when the middle of the brownish black one i thought the white could could potentially move through that hole if it were made thiner and longer and we know a copy of itself doesn't necessarily mean we're going through it like this way we're just going to thin it out to the size of the hole of the beginning though this video shows a way todo so
This could be easily reworked into a surreal meme.
okay, that was quite surprising!!
Any machinists who have got the chops to make this? Those sharp internal corners and clamping it without folding it in half would certainly make it challenging.
No 3d printing. Metal only!
This wouldn't work because if all sides of both cubes are equal, you would just end up with what are essentially the "leftovers" of cutting out enough space for the other cube to fit through. Being the exact same size, there would be nothing left connecting the additional pieces left by making the hole. In addition, a shadow changes the area it covers depending on where the light it positioned.
Ok, now this is epic
And that, boys and girls, is how babies are made.
Yes this is the sex
Wow fits just like a cube...
This video is therapeutic
The black cube just put on some fucking armor
Damn... Stewie's teddy bear is pretty fucking smart.
Came for the video, stayed for the music
Absolute madman
That just blew my mind
Does the hole fit exactly inside the cube (with the remaining parts just touching edges), or is there a there a “finitesimal” margin of error? It’s hard to tell.
this is the reason why drain covers arent square but circular. I know square and cube isnt same but by rotating a square drain cover a certain way, it will fall through the square hole.
I'm pretty sure the reason why drain cover is circular is because the radius is the same even though you measure it from any where. It'll fit the hole no matter from what direction you close it.
Meanwhile if the drain cover is square it will become "less efficient" because you have to close it in certain direction in order to fit it in the hole.
P.S. i'm sorry if my explanation is too complicated because english isn't my first language.
So bootiful
Fabulso!!! Impresionante!!! Maravilloso, gracias por compartir
Magnificent!
You are so genius.
Turning the "move" cube about 45 degrees on one axis would all much more material for the "passed-through" cube to remain.
This so trippy for some reason
Anything that is geometry is conspiracy theory fuel
This video betrayed my entire childhood.
That's pretty neat.
That’s a sharp bend
My life has changed
Mind blown 🤯!!!!!!!!!
IS THAT MOONLIT NIGHT I'M HEARING!? Very interesting anyway
GENIUS.
Just imagine a set of such cubes passing through each other. I'm also curious how it works with other figures, which figures have this property, and also whether these properties have some utility.
I started loving your videos 💖💖💖
It's beautiful
This is pretty damn clever
Wow, this is very and very interesting for me.
Hell yeah
This is amazing
i realized that answer just before they gave it out
wow, by the same person who made prince rupert's drop!
This video made me extremely unsettled! Very cool, though!
Kenisowilo haha thank you:)
Yes it is possible to fit it because they never specified whether you could cut both down smaller or not
