Walls that pee back!

Pee On This Wall, It Pees Back At You
  • People in Germany came up with an idea in which they covered walls with super hydrophobic paint. So all the pee is splashed back over the person peeing.
  • Originally developed by Nissan to keep cars clean from dirt, the water-repellent paint acts as a reflector.
  • It costs about $700 to cover six square meters with urine-repelling paint.
  • According to Ultra-Ever Dry, a paint manufacturer, an object coated with hydrophobic paint develops a surface chemistry and texture with patterns of geometric shapes that have “peaks” or “high points”. These repel water, some oils, wet concrete and other liquids.
