Frank–Kasper phases

So imagine you have some really cool building blocks, like LEGO, but instead of bulky rectangles, they are all shaped like little pyramids. Now let's say you want to build something with them so you start trying to stack them up. As you stack them you notice that sometimes they fit together really well and make a strong structure, but sometimes they don't fit together very well and the structure falls apart.

Scientists have found that some materials made of little pyramid-shaped building blocks do the same thing. But instead of just falling apart, they actually form specific patterns called "Frank-Kasper phases". It's kind of like a puzzle where the blocks fit together to make specific shapes, like a honeycomb or a diamond pattern.

These Frank-Kasper phases are really important because they can help us understand how different materials behave and why some are stronger or more rigid than others. So scientists study them to learn more about how materials work and how we can use them to build cool things like stronger buildings or better electronics.
