Tungsten Fidget Spinner Upgrade


Because tungsten is really heavy, and more mass means more momentum. It’s heavier than spent uranium and twice as heavy as steel. A tungsten slug that is the same size as a 608 bearing weighs 450% more. This is the secret to super long spin times. No matter how good your bearing is, a tungsten loaded spinner will always spin longer.
