Try to solve the following enigma. The following piece of aluminium was neither thinned not elongated. And no pieces were added. It was not a sphere or a cylinder. So how can it have this shape now?

chain
why bother bending the whole frame when you can just bend the centre pieces? cut the sheet like in the following (Fantastic) diagram and then bend them towards the middle?

it’ll take less effort ;)
yeah i don’t think we’ve got it quite yet. cos if that’s the answer then that’s just stupid. it’s gotta be more ingenious than that to put on display.
heated and bent?
the liquid alliminium was poured into a mold,
not that hard
easy!!! it was like this:

ummm.. can any of you say….”welded” It is very obvious by seeing it the word in the pic also.
Its cleverl but rather simple, cut from a sphere. Think of it as globe frame (with grid rather than full solid) say cut the globe at +20 degress Lattitude and -20 degrees lattitude and +30 degrees (u could still use 20 as such) longitude and -30 degrees longitude. That will form a rectangle of sorts with long mid section and small top and bottom sections.In order to make it a real rectangle you would have to cut the mid sections which forms the douple layer (of the middle horizontal strips) that’s shown here. The rivets are just for show.
Clever..aiye!!!
im confuzzeled. was it welded? bent? overlapping the someone stuck it up? does anyone really know 4 sure except the person that did it? no one really knows for sure.
The Vulva warped it to it’s current shape.
its against a mirror
The answer is within your own mind’s eye, if you can remember the word ‘reflection’ on the top end of the picture. To reflect the top horizontal strip will give an added dimension that sends the human mind’s eye on vacation for a moment… then it becomes obvious, in my mind’s eye, anyway…
REFLECTION FROM BENEATH!
wat if it’s just a picture? and not aluminium at all??
That is stupid
2 pieces of metal, one on top of the other.
Its in plain view that way!
It’s carved from a block of metal.
omg Photoshop.
what JB said at the top is correct… the bottom strips at the bottom are not bent they are over lapping but on the top they are bent up and held together quite clearly by what I believe is a bolt… placed through the holes…..
Never mind, I see what is being asked now, forgive me… I am not sure how this would be done then with out doing what Yo said
Chain I like your theory the most, it makes sence… and it is a an object, not just photoshop or mirrors….
It has been cast and then bent into shape
Connie you idiot, It says, no welds in the explanation. Chain makes the most sense, given the circumstances. The rest of you are pathetic.
yeh u can tell that they were overlapping – and that on the bottom strip they r overlapping
I don’t know whether anybody will be bothered to look down this far because I didn’t so i don’t know if this had been said or not.
I can see one possible weld joint on the bottom right corner. But i can’t see one at the top.
I was in wanaka yesterday and spent ages agonising over it. I like chains explanation in 42 and i did notice some evidane of deformation in the corners. The staff there will not tell you the solution but if you give them an explanation they will say if your right.
How about this shape?

I just want to say: “READ the other posts BEFORE posting your own comment.”
I too believe Chain is correct in his theory, and him having post 42 makes it just a bit more likely (Answer to life, the Universe and Everything.)
Somebody thought about Photoshop?
I’m thinking that maybe it was cut similar to this:
|=======|
|…….|
|=======|
|=======|
|…….|
|=======|
|=======|
|…….|
|=======|
Where the single cut is a top bar, a bottom bar, and two inner “double bars” each separated from the frame opposite their partner. From there you would lift each of the inner ones and overlap them. (bad text example:)
|=======|
|…….|
|===\ |
| \===|
|…….|
|===\ |
| \===|
|…….|
|=======|
Depending on the width of the whole sheet or the angle you view it at, it would *appear* that the doubled up single inner bars meet the sides at the same point on either side. In this picture, in fact, it almost appears as though the lower unbent doubled up bar is higher on the right side than it is on the left. It’s hard to tell from this picture though.
Me no get it…
it is easy to figure out if you just look at the other strip of metal, there are actually two strips of metal and one is going across the other!
theres two peices of metal on the straight one you dipshits
they just didnt add the screws, bent them upwards and ‘tried’ to fool you
laaaame illusion
expecially since i can see the ‘trick’ without someone having to tell me
um.. a possible way of doing this is by creating that sheet of aluminum with four normal arms and then cutting through from the left side of the arms along their thickness…(it really is difficult to explain in mere words..)Just so u get the ill point out that after the work is done, the thickness(not the width, not the length, the THICKNESS) of the overlapping arms will be half the thickness of the rest of the thing.. This is why it is almost impossible to do it with paper(like one of them here pointed out..) because paper alreay it too thin and u cant cut through its thickness (unless its some sort of “two-ply” tissue paper or something..)
Ani has got it. It’s a symmetrical object so think about reflection and think laterally about what it might mean to “cut” a sheet of metal. How many ways can you cut a sheet 8mm thick? Horizontally? Vertically? Laterally?!
To anyone who has said ‘Photoshop’. Do the world a favour and stop breathing. This is an actual physical exhibit. Having seen it myself in Wanaka I think that Chain (no. 42) has offered the only sensible solution in relation to the actual problem, which I have to say isn’t clearly defined on this page.
Following on the idea that Chain(42) gave I think i also have a possible answer: Imagine a flat but elliptical shape of aluminium sheet. Now take the shape in question and “elliptically” apply is to the elliptical sheet of aluminium (i.e. the long sides of the sheet in question was the short sides of the elliptical sheet of aluminium). With a little bit of tapping on the short sides of the elliptical sheet, you can bend them to become straight but ofcourse the inside bars would them overlap, which is exactly what we want! The longer edges of the elliptical sheet was simply cut off straight to form the short sides of the sheet in question!! :)
ohhhhhkay… we have metal of all kinds, tooled and died into technological marvels like internal combustion engines, spacecraft, automatic weapons, or precision clockwork, and you all are marveling at a piece of aluminum with overlapping bars. arguably not an easy task but hardly worth any disbelief, i should think.
It’s called welding. ^_^
quite good explanation from Chain(#42) yet one certain factor affects the theory(an aluminum sheet from parallelogram to rectangular shape) w/c is deformation on its corners!if the cutting pattern is done precisely wherein the slant width of the parallelogram is almost vertical then fabricating this cut piece into its final form a rectangular shape will have a negligible deformation!you can check me out if you want the visualisation of the cut out piece.(autocad program)
The bent rhombus idea makes the most sense.
What optical illusion are they talking about.
The lower portion has two overlapping pieces whereas the top portion they didn’t overlap and they just screwed them together.
tsk tsk tsk tsk Its NOT VERY Hard Look at the other one thats strapped down…cant you see its overlapped?? Duuuuuh All we have to do is just unscrew those nails holding them down try to bend both of them the oposite dirrection and then when there good enough let go and they slam together creating what you see now
REMEMBER Illusions are simpiliar then you think!
thanks luke and all those who saw it before. the bottom cross section has another piece underneath it. the top was placed like that, might have been tacked but i doubt it.
It’s two pieces of aluminum overlapping each other that have been lifted up to lean against each other. The cross bar shows two pieces overlapping below. Sorry, but this one was really obvious…
