My New Car Potty

A few months ago I saw a dishwasher detergent container upcycle on Pinterest in which the pinner turned it into a trash bin for her car. My first thought: ummmm...have you seen my car? I don't think that's going to be big enough. My second thought: self-contained potty jug! The opening is big, it can be closed, and you can line it with an old, unused diaper to soak up the pee so it doesn't spill (it sure beats holding the diaper in the shape of a urinal in front of your kid and telling him in vain, "aim here").
