Beer slows your reaction time!

In one nanosecond, light travels about 22.26 cm in beer.
(Beer has a refractive index of 1.3466).

In one nanosecond, light travels exactly 29.9792458 cm in a vacuum.
(Refractive index of a vacuum is defined as having a value of 1.0).

In one nanosecond, light travels about 29.89 cm in air.
(Refractive index of air is 1.003).

The exclusion of water from this theory was intentional.
(RI 1.33).
