Namib Desert Beetle

The Namib Desert Beetle lives in such a dry environment that its skin on its forewings has micro grooves that capture water vapor in the air to allow it to have another source of water,(from the air). “The shell is covered in tiny bumps that are water attracting (hydrophilic) at their tips and water-repelling (hydrophobic) at their sides. ”  There are engineers now attempting to use biomimicry to create a self-filling water bottle. The beetle has also inspired an irrigation system which creates condensation at plants roots.

It seems this water bottle has been shown to be a scam
