Light normally travels at 299,792,458 meters per second in a vacuum, but has been recorded traveling as slow as 17 meters per second when passing through a Bose-Einstein condensate cooled to near absolute zero. Light also slows slightly when passing through materials like glass, which allows it to bend and enables the creation of lenses.

Incidentally, the slowest light has ever been recorded travelling was 17 meters per second, through a rubidium, cooled to almost absolute zero, when it forms a strange state of matter called a Bose-Einstein condensate. In glasses, light slows down a bit, bending its trajectory and allowing the making of lenses. 12
