Steel Balls, 1″ (25mm)

Solid Steel balls with diameter of one inch (about 25 millimeters) are used in mechanics and magnetism experiments. They are also used in construction of pendulums and demonstration of Newton laws and physics experiments related to Inertia, mass and friction. Note: Steel balls can rust if they get wet or in high humidity conditions. Keep them dry and wax them with mineral oil for long term storage.
