Saw a video of a person pulled a shard of metal out of a liquid, looked really cool and wanted to know how they form?

Melt bismuth, slowly cool it on a seed item or a metal stick as you pull it out slowly it’ll form different shapes and sizes (but almost always 90* angles) depending on the temperature and how close to crystallizing it is.
There’s also molds for making different shapes that are silicone so they’re easy to take out and reuse the molds
