Corrected entry: When Frank and Jim are on the rooftop and Frank is talking about collecting rainwater, you can see covered containers among the receptacles. You won't collect too much rainwater with a covered plastic box. (00:39:00)

Correction: He covers the containers between showers to prevent them from evaporating. You won't collect much rainwater if you let it evaporate away.
