Gozinta Boxes of Lubor Fiedler

This is incredible. How is this even possible? Identical boxes are not really identical. These Two Boxes Fit Inside Each Other!
The Gozinta Boxes are a topological magic trick invented by Lubor Fiedler in 1966 and first introduced at the 1970 FISM convention in Amsterdam. In this trick, a die box is removed from a box. The positions are subsequently reversed and the outer box is now placed inside the die, creating a paradoxical situation. Gozinta Boxes of Lubor Fiedler

The sides are not perfect squares. They are rectangles. That game is just for stimulate the mind of the japanesse kids.

[@veproject1]

I just want to draw your attention to how accurately the dimensions are calculated. After all, if you make a mistake by a millimeter, the boxes will not fit one into the other.

[@RobertSzasz]

The larger the "cube" the closer to a cube it could be.

[@joshi2438]

First these dimensions aren't that accurate you can see these aren't cubes so they probably differ some mm on each side I wouldn't call that very accurate when you can achieve some 0,5 mm differences with not to expensive manufacturing and second who are this videos for? For kids they should be explained in the end or they are just baffled for normal people this feels like it's made for kids but again if it's for kids I don't think it's good and the other perpetual motion machines are even worse I really don't understand what's happening here

[@regisvoiclair]

Ridiculous ! : the boxes are simply not cubic: seen from above, they are rectangular.

[@Onozitsthpopo]

Actually it's black magic

[@Onozitsthpopo]

Some will say is because the boxes are rectangular prisms instead of cubes. This is just what THEY want you to believe. The truth is it's black magic ✨

[@darrenhadden1037]

wow awesome!

[@mikean1123]

They are exactly the same. If you only measure 2 sides

[@DeltaZavr.]

Белецкий у себя объяснял, что они разного размера просто.

[@gosic007]

Так оно и есть, это не квадраты, а прямоугольники.

[@user-qw2dm3yl8s]

А тонатр радостный запихал прямоугольник один в другой.

What is the name of Japanese professor ?

Tem a ver com elasticidade também

[@Eduardo_eduardo]

As caixas não são cubos, mas retangulares.

[@Oslashio]

sepertinya balok

[@robertmcdonnold3038]

The boxes are not perfectly square. Not the same dimension on all sides.

[@ProcXelA]

Pocket measurements. It is obvious.

[@SlavaSomov]

Wrong title. That is not a cubes. And nothing incredible there because of that

[@ramonhamm3885]

They call them boxes not cubes, that's fair.

[@SlavaSomov]

@@ramonhamm3885 They changed the title after my comment. This was almost a year ago.

[@ramonhamm3885]

They are not prefect Cubes

Tiktok quality kind of content there together with the horrible text to speech :(
