Tungsten Fidget Spinner Upgrade


Because tungsten is really heavy, and more mass means more momentum. This is the secret to super long spin times. Tungsten weighs twice as much as steel and is even heavier than depleted uranium. A 22mm x 7mm tungsten slug is the same size as a 608 bearing, but weighs 450% more. No matter how good your center bearing is, a tungsten loaded spinner will always spin longer.
