PRENDEMOS a LUZ numa CAIXA de 12 ESPELHOS

Today we are going to build this object that practically multiplies the dimensions that we know. It creates new universes! If you watch Manual do Mundo, you must remember that here we have already created some portals to infinity. The first one was made with a mirror, some Christmas lights… Then we made an infinite cube using several LEDs and semi-mirrors, and I'll confess That I really regret having disassembled this one… But today, in partnership with Disney+, I'm going to get rid of that regret because We're going to build something much cooler based on a dodecahedron. Dodeco what? A dodecahedron is an object with this shape over here. Mathematically, we say that It is a solid with 12 faces. But this one here is a special dodecahedron, because It came from, it's what was actually used in the Mila in the Multiverse series. This Is the new Brazilian fiction series that was launched in January on Disney+ and there this object is called pollen. It was created by Mila's mother who is the protagonist of the series. Her mother is a scientist who discovered how to travel to other universes. And it's using pollen that Mila ends up going on an adventure in a completely different Universe to try to find her own mother with the help of her friends. When Disney+ spoke to us, it showed some scenes from the series, it made us want to Build our own pollen, but there's a detail, right? That in real life you still can't Travel between different universes… But this is the Manual do Mundo, so we decided To find a way and at least create an object in which we could travel to different dimensions. We want to use a dodecahedron because it has many more faces than a cube, so when You look at the cube, you notice that it has six faces, and the dodecahedron has 12. This can give a much cooler infinity mirror effect. And for us to install all the lights inside, it can't be small. How big do we make this, huh? We made some measurements, some calculations and discovered that the minimum size We can work with is pentagons that are 18 cm on each side. The skeleton of our pollen will be made of MDF, we will cut 12 pentagons in the laser And the idea is to put all this together here, which I think will not be an easy task… This weird triangle you see here is a guide for us to make the angle between one part and another exact. It has to be 116.565 degrees. The first glue I will always do with super glue and baking soda to fix it in the right Position, and then I reinforce it with hot glue.

That, after all, is what will hold the structure. When I glue only two, it's kind of waek, but when I put the third one, it gets stronger, And I hope that when we put everything in, it'll have a good structure. The problem is that now everything fits. When we get to the end, in the last pieces, you will realize that you made a mistake… because then they don't fit. Now it only has four parts, and it is now that we see if it worked. Just need to put everything together now. Every corner. Let's go one by one. Look at the size of the dodecahedron! I think pollen of this size would be difficult for Mila to carry back, huh? It's much more practical to be small. For lighting, we prepared something supercharged here too. We are not going to use Ordinary LED. It's going to be an addressable LED. You can control every point of It with Arduino, and then you can make some drawings, you can do something crazier Than what we did before. In fact, these pieces here we took from that screen that We made in our series about computers. An important step is to paint the structure Black, place some reinforcements and attach the pieces of LED strip. Each tape has Six solder points. There are three at each end, and then we connect one to the other And then connect all of this to the Arduino. To close the dodecahedron, we're going To use acrylic that we also cut with the laser, but the real secret is here, look! It is this film that is semi-mirrored, it is a mirror that does not work 100%. If You look at it from this side, it's a mirror, it looks like the light is reflecting 100%. But if you turn it around, look… part of the light passes through. This mirrored Part faces inwards, so when we turn on a light here, you will be able to see a part Of this light, which I'm looking at here. The other part it reflects and comes back Here, you can see it too, but then you are already seeing a second image. But it Also reflects here, comes back and goes again. Then you already see a third image… And so on, in the end, you put a light bulb, but the feeling is that there are infinite Light bulbs one after the other. Installing it is quite complicated. It's like installing Film in a car. First, you have to clean the acrylic well, not leaving any hairs, I'm doing this with isopropyl alcohol. Then, you have to throw some water with detergent On top, go there in the film and remove a transparent film that has on the front. The problem is that this mirrored part is full of glue, so you have to throw soapy

Water again. So nothing sticks, then I put it on top of the acrylic, and I'm taking The water from the center to the edges. In the end, you have to check that there Are no bubbles left inside. Looks like it didn't, but I'm sure it did. We thought a lot about what we were going to use to attach this plane to the skeleton. Hot glue would escape, super glue is not enough, it does not give mass… In the End, this tape here was the best option, but I'm afraid that light will leak. One detail of a pentagon is that they don't fit in the plane, so when you put them On the table, you can't form a pretty thing, like a beehive, because in the beehive it's a hexagon, not a pentagon. As the dodecahedron has 12 pentagons on the faces, there are a total of 30 led strips that are in this skeleton. In mathematics, each such strip is an edge. And where these edges meet, we weld the tapes together. These points, a math teacher would call the vertex. We separated these LEDs into four sets. Now, I'm going to temporarily switch on here just to see the thing lighting up to see if there's any bad contact. One two three… Wow! It's really cool. Let's try to take a long exposure photo here, it's a photo where the camera is open taking for a second or so. We can draw with light. It's even a pity to put a mirror on this here. We found that these double-sided tapes are longer than they should be, they are wider. Now we have to cut everything in half and remove what was already stuck. First board. What a crazy thing! Last test before fixing this yarn mafagafo here.. Let me turn off, let me turn off… No, you can't give spoilers like that. It's pretty crazy. Now that we're going to activate our pollen, I'm sure you must be eager to see Mila's working too. In the series, she and her friends study at a very cool biological institute in the multiverse, do a lot of experiments… Makes me want to visit this place. So, run to Disney+ and take the opportunity to watch all the episodes of this Brazilian Series that talks about science and adventure. Because if you like Manual do Mundo, You'll love these themes too. Including, if you want to venture into making one

Of these here, we're leaving all the plans, how it was cut, the materials that go Here in the description, ok? Then if you do, take a photo and tag us on Instagram with #MilanoMultiverso, ok? If this isn't worth a thumbs up, I don't know what's worth a thumbs up. I'm going to try to make a thing here that I shouldn't try, but I can't resist. Wow, now I'm in the multiverse. What a crazy thing!
