If you don’t know the maximum safe RPM of an object, spinning it too fast can turn it into a deadly weapon. This is caused by centrifugal force — the powerful outward force created when an object rotates. Every material has a limit to how much force it can withstand. Once that limit is exceeded… it shatters instantly. ✔ A skateboard wheel can explode at 45,000 RPM ✔ A vinyl record shatters around 80,000 RPM ✔ Even steel ball bearings — thought to be indestructible — can burst apart near 150,000
