# Origami vs "Magic Edges" sets

In this article we will try to tell whether the of “Magic Edges” can be attributed to a variety of origami. As the same geometric shape can be obtained using parts from the "Magic edges" and using the technique of origami. What are the pros and cons and what are the differences?
For the uninitiated look, the impression may appear that the paper models of polyhedra in their performance do not differ much from each other. Meanwhile, if we take for more careful comparison two common techniques from the arsenal of “paper creativity” - modeling and origami, then we will find a significant difference in the approaches, which make them fundamentally dissimilar.

So, modeling from paper, and the set "Magic Edges" refers to its number, in its approach it preliminarily "parses" the spatial figure into fragments-scanning. Transferred to paper nets cut, bend and glue. The junction at one of the surfaces has an overlap - valve. The valve from the junction to the adjacent part is coated with glue. Consistently glued surfaces eventually form a solid structure.

The technique of origami, in any case, in its classical version, does not imply that the paper is cut and joined with glue. Paper sheets, most often square in shape, are folded in such a way that the friction in the folds keeps the figure assembled, preventing it from falling apart.

In the case of origami, its “modular” variety deserves special attention, since it is best applied to the creation of polyhedra. In modular origami, several sheets of paper are used in the folding process. The number of such sheets can be very large and depends on the number of modules in the design of the assembled figure. A peculiar embodiment of the very principle of modular origami is the Sonobe module, which is a parallelogram folded from a square sheet with two pockets for connecting it with similar modules. The variety of spatial bodies created on the basis of the Sonobe module is infinitely large, but they all consist of one element, leading to the uniformity of the surfaces forming the figure. Each technique has its limitations and one cannot say about the definite advantage of one of them.
However, as an obvious one, continuing the comparison of origami with the set “Magic Edges”, we can note that, in the case of origami, due to multiple folds, it is difficult to work with thick paper. True, the origami technique does not require the use of glue in the work and, therefore, does not put us in front of the difficulty in choosing the latter. But, on the other hand, origami implies an independent search for suitable paper, as well as the choice of schemes, mastering the most complex and interesting of which will require considerable time and certain skills.

The set "Magic Edges" is made on a glossy cardboard with high quality color printing. The contours of the developmental parts are partially cut and easily separated by simply pressing them with your fingers. All materials for self-assembly are prefaced with illustrated instruction and a historical excursion mentioning curious information about the discovery of a particular polyhedron figure and the mathematicians involved in this discovery. Intelligently and clearly!

This suggests the conclusion that a greater cognitive effect can be extracted from the set of “Magic Edges”, which supplies information in a systematic way. We are dealing with an excellent means of educating spatial thinking, able to simultaneously strengthen the relationship with the child during your joint creative development of the proposed material!
