3D objects are among the most difficutl projects you can attempt. Especially if you're going for a Youtube record. This 27x27 domino pyramid (see picture), which was not finished, was built by me and my friend Alex. But there are other 3D objects, too, such as cubes, walls and towers. All those stackings are based on a "1x1 tower". This simple technique is the
basic principle for any other stacking. So in a way, they are all just variations. On this page, I'm going to show you three stackings.
This kind of stacking started quite a competition on YouTube. Basically every well-known domino-builder attempted the record. The biggest one so far was a 30x30 pyramid set up by DominoDayTV. As the number of dominoes needed for the 3D building increases exponentially, a 30x30 pyramid requires 18,445 dominoes and a 32x32 pyramid would already included 22,352 dominoes. So with 30x30, there's not much room for bigger records if you ask me. Hardly any domino-builder even owns that many dominoes. The pictures here show how to build a 3D pyramid.
The cube is hardly different than the stackng of a cube. It is the base and the heigth that make the difference as to what kind of building is standing in the domino room in the end. A tower needs as least 2x4 dominoes in the base (see picture) and can be continued as long as you want. However, the taller it gets, the less stable a tower is. That's why the base of the world record tower made by dominoschulrekord had a size of 8x16 dominoes. It was nearly 17 feet tall. In the pictures, you see step by step how to build a tower or cube.
There are two different kinds of walls; one that topples slowly and one that topples fast, the so-called "speedwalls".
