Sanden Totten, KPCC's science reporter, took one for the team the other day. Took a shower, that is.
With his girlfriend holding the mike and the stopwatch, Sanden tried a Navy shower - using water only when needed (wetting hair, rinsing), and shutting it off when not needed (lathering hair, scrubbing between toes).
Find out how much water he saved compared to a regular shower, and then hear his interview with an astronaut to find out how much water, it turns out, he wasted.
