The original SLIPS materials also need to be fastened somehow to existing surfaces, which is often not easy.
"It would be easier to take the existing surface and treat it in a certain way to make it slippery," Vogel explained.
Vogel, Aizenberg, and their colleagues sought to develop a coating that accomplishes this and works as SLIPS does. SLIPS's thin layer of liquid lubricant allows liquids to flow easily over the surface, much as a thin layer of water in an ice rink helps an ice skater glide.
