Hi, and welcome to another episode of Mr. Puzzle. Today, we will have a look at this puzzle here, and this is the “The Cell” puzzle, which I received from Puzzle Max dot com. And the puzzle itself consists out of two parts. One is this tetrahedron-shaped part here in the inside, and the other one is this cell on the outside. And the target of this puzzle is to remove this tetrahedron shaped part from the inside, and take it out. It is actually a simple puzzle, but, not for everyone. When you give this to some, someone who is not, or, who is weak in dimensional thinking, you will have a lot of fun watching him how to get it, get it out. How to do it I will show you after the spoiler break. Okay, how to get it out? When you look from the top, it is obviously, in this condition, not possible to get it out at all. You try to get it out, you can see it will get stuck because it’s just too big to get out to the top. Some of these edges will always interfere here with the frame. But there is a trick, of course, which is pretty simple, but for some people hard to imagine. And this is you need to turn this tetrahedron shape into a square to get it out, squared shape. And how can we do that? Well, you need to imagine this tetrahedron as a two-dimensional shape, so when we look from the top on it, in two dimensions, you only see a, a triangle, nothing else. But, if we change the orientation of this triangle, or of this tetrahedron, and look from it from the top, we will get another shape. I just take it out now. I’m not sure if you will be able to see it. But you will be able to see it better when I put it back together. So now I took it out. I’m not sure if you have seen how I did it. When I put it here on the top, you still can see it does not fit at all. In no condition I can put it in. But what I mentioned before, you have to ima-, if you imagine this one as a three-dimensional shape, you have now the triangle, another triangle, but if you move it in the right orientation, and this means in this orientation, you have actually, it moved, it turns into a square. In two dimensions, you can see here two equal, eh, four equal sided, four equal sides and the square. And this fits exactly inside the cell. And that’s the trick. Simple, but nice, from my point of view. Regarding the difficulty, from my point of view, it was, it is only a one out of five. But it’s still worth to try it. And it’s a lot of fun to see people fail on this one actually! So I will put you the link where you can buy this one in the description. The website is Puzzle Max dot com.
