(Scroll down for video) People who hate leaving behind drops of shampoo in nearly empty bottles, will soon be able to purchase plastic shampoo bottles that empty themselves to the last drop.

Researchers at the Ohio State University, have developed a new coating for plastic bottles to make soap products flow freely from the inside.

The new patent-pending technology restricts the soap from touching the inside of the bottle. The researchers developed the structure using nanoparticles, which do not stick to soap.

The development is part of a project to create a shampoo bottle that is efficient and environmentally friendly. The researchers hope to license the coating technique to manufacturers for other bottled plastic products.

The method has already been applied to polycarbonate, a plastic used in car headlights and cases of smartphones, among other applications.
