Magic rings are also called Umulius Rectangulum, whatever that is. It seems like the paper “rings” are impossibly intersecting, but actually it’s made from 6 pieces, the intersections are hidden between them. The modules are made from half of an A4 paper. I used a thicker paper than normal printing paper to make it, very sturdy. At first when both ends of a module are connected, or when 2 modules are connected, it wont necessarily hold together, but once it’s assembled the intersecting modules keep it falling apart. Made by Thoki Yenn.
The paper has to be folded in 5 lengthwise, since I didn’t know how to do it I used a ruler to divide it before I folded.
Diagrams here and video after the break.

I made this before and I remember that there is a way to fold it in fifths, I’m just trying to remember. I’ll work on finding it, but I know there was a video of this on youtube. I also remember seeing how to get a letter sized paper into A4 but again I don’t remember how.
But good job - it looks amazing.
Yeah I know how to fold it in fifths. Adamssara found a method:P
Here’s how to fold into fifths for everyone who don’t want to use ruler. Link here
@Helper: thanks, although it still works with an “estimation” it’s far better than a ruler.
Please schematize the measures better otherwise is difficult to carry out the pattern. to show the diagram with the measures and proportions.
thank you
can you send me some printable magic ring instructions PLEASE!!
@Evan: I’m sorry, but I don’t have to distribution rights, it would be much easier to take a ruler and make it yourself.
hey its me where do u get a4v paper i live in america and whe use 8 1/2 x 11 inch paper so it doesent work for me plz plz plz respond
@david: well A4 is an international standard… this is the format used in countries using the IS metric system, I don’t know abut the US.
You can work it out on a letter sized paper too, this model depends on the ratio of the paper, an A4 paper ratio is 1 to square root of 2, so the ratio you’re looking for is 1 to the square root of 2 divided by 2. An easier notation: 1 to Sqrt(2)/2.
huh?? can u just tell me how many inches if normal is 8 1/2 X 11
Well I’m not sure, so I asked God: http://www.google.ch/search?hl=en&q=11+inches+multiplied+by+square+root+of+2+divided+by+2+in+inches
The A4 format paper, i cut it in half so i measured it i came up with 10.8 c.m, then divided it into 5 parts and i came up with 2.1 and a half millimeters. So thats the way i did it. I just said it to be easier.
can u just tell me the deminsions of A4 paper cut in half lengthwise will be if i used 8 1/2 x 11 paper plz
@david: I explained it already and gave you the answer, this is basic math.
In the diagrams web site http://www.britishorigami.info/academic/thok/billumu.html you find the following explanation about the name. “…After having explained to Mr. Andrew Hans, that the word Umulius is a Danish-Latin form of an impossibility or an impossible person…..”
David: I should lecture you on the mathematics (not even that; it is arithmetic) but I will be friendly and just give you the darn answer. You have waited a while for it :)
Short answer: cut the paper to 11 inches by 7.778… inches. This is the dimension for an A4 (as Karl gave you in the search results.) I have noted that for this model, a dollar bill is about the right proportion. Look at my website origamisquared.googlepages.com to see an example of this model with dollar bills. Alternatively, use Google. It is a very nice tool.
Long answer: The 1 by sqrt(2) is a proportion. It doesn’t mean one inch by sqrt(2) inches; it means any multiple of 1 by sqrt(2). Because the longest side length you have is 11 inches, the other side should be 11 times sqrt(2) inches (because the ratio is 1 by sqrt(2)), or as Karl offered, 7.78…inches. Hope this helps you!
Hey i found a method on how to make a square piece of paper, to an A4 format. Diagrams on origami.com the first one.
can you send me some printable magic ring instructions PLEASE!!
wut was the mesurement of the paper u used.
Does anyone know the dimensions to use this model with square Stickys? (p_st-its is copyrighted)
