Nowadays it is used, beside the self admiration, in cameras, telescopes and satellites.
When the man first went to the moon, they left a mirror there, so today using a laser is possible to measure the distance earth moon very accurately.
This videos shows how to make a mirror by using the glucose to reduce a silver complex. The metallic silver is deposited in the flask forming a mirror’s surface.
