A tall tree looms over my property. Bats eat its fruit then dump their purple poop on my sidewalk. Bleach removes the stains in seconds. But dilute the bleach by a factor of five and nothing happens. I thought it would take five times longer to have the same effect. Nope, nothing doing. Can anyone suggest an experiment that might explain this?
