Watch How Balls of Steel Are Made

If there’s something more satisfying than watching hyper-specific machinery churn out random parts, I haven’t found it yet. In this behind the scenes video, one of Shandong Iraeta’s factories tirelessly turns giant rods of metal into perfectly spherical balls of steel.


At one point in the process, the steel balls, which are used in rotating drums as a grinding and polishing material, look like puffy clown noses making their way up a conveyor belt. But in reality that’s just raw steel that’s been heated red-hot to make it malleable. Squeezing a clown’s nose is fun, but squeezing these would make it impossible for you to use a fingerprint reader ever again.
