A group of scientists in China have created an ultra-slippery toilet bowl that can repel almost any type of liquids or solids.

Porous? How does that work for making a surface more slippery?
From what I skimmed, its slippery properties comes from mainly "hydrophobic silica powder distributed among polypropylene powder. Silicone oil is sprayed afterwards to protect it from abrasion and other mechanical force. Even it wears down, all components (hydrophobic silica and lubricant oil) are present on new surface because it’s built porous so the slippery property will be maintained.
