As part of its effort to help save the planet from the dangers of taking too many baths, the EPA's WaterSense program is trying to convince kids they should avoid bathtubs in favor of showers, which it says is a far more efficient use of water.

"To save even more water, keep your shower under five minutes long—try timing yourself with a clock next time you hop in!" the "WaterSense for Kids" website says.

In addition to convincing kids to stay away from the tub, the EPA's website instructs children to be careful not to give plants or the yard too much water, to ask parents to use car washes that recycle used water, and to avoid using hoses whenever possible. The EPA even suggests kids conduct experiments with parents to test toilets for leaks.

When kids aren't busy timing their showers to ensure they remain as unclean as possible and training to be future plumbers, they can "test" their "water sense" by playing EPA's Pac-Man-inspired online game starring the "water-efficiency hero," Flo. The goal of the game is to move Flo, a cartoon water drop, "through water pipes and answer water-efficiency questions while avoiding water-wasting monsters."
