Flux has ordered 100x4mm (0.2610g) and 100x5mm (0.5099g) high grade steel ball bearings for experimentation. | Current favourite is the different sized ball bearings. A small difference in diameter results in a large change in mass. Flux has ordered 100x4mm (0.2610g) and 100x5mm (0.5099g) high grade steel ball bearings for experimentation. | ||
