From the So Obvious I Can’t Believe I’m Writing This Down file:
I’m fine with tap water (especially with the help of my beloved Brita filter pitcher), but my husband is a devoted bottled water drinker. The kids, too, like bottled water as a treat, and we often have a bottle or two in the car. Problem: several day-old bottles sitting around with three inches of water left in them.
Unrelated-but-relevant problem: We have four neglected houseplants that I forget to water.
Well, this genius finally put two and two together, so now, whenever I find an old water bottle sitting around, I dump the remainder into the nearest plant and recycle the bottle. Two problems solved at once. Easy for kids to do themselves, too.
