New artificial substance could make condiments slide out more easily

Slippery Liquid-infused Porous Surfaces

I’ve heard countless tricks on how to get the last drops of sauce out of the ketchup bottle. I’ve been trying those for a while now, no success. Now, here’s some good news.

Scientists at Harvard University have made progress in the development of a super-slippery material, which could prevent food from sticking to the insides of containers. The folks behind the research were inspired by the Nepenthes, (popularly known as tropical pitcher plants) whose slippery leaves slide insects into the digestive juices at the base of the plant.

The artificial substance, called SLIPS (slippery liquid-infused porous surfaces), repels almost any type of liquid, including blood and oil, meaning condiments such as ketchup slide off it easily without leaving any residue.
