Shampoo bottle that empties completely, every last drop

Researchers have found a way to create the perfect texture inside plastic bottles to let soap products flow freely. The technique involves lining a plastic bottle with microscopic y-shaped structures that cradle the droplets of soap aloft above tiny air pockets, so that the soap never actually touches the inside of the bottle. The "y" structures are built up using much smaller nanoparticles made of silica, or quartz -- an ingredient in glass -- which, when treated further, won't stick to soap.
