A sphere coated with the material Vantablack, adapts to end a metal rod and becomes invisible when it passes over a surface with the same hardware.

The Vantablack, is a material manufactured by the British company Surrey NanoSystems and sets a world record, absorbing 99,965% of the visible light. It is made of carbon nanofibres which is 1.000 times thinner than a human hair. Tiny tubes are small enough to prevent light from entering and are so close to each other so the light bounces within them to be absorbed.

   (E), not that the small tubes prevent the entry of light... They probably allow it because then we say that it 'bounces inside'
