Notice how this piece of bread—shared by Reddit user lo_and_be in the Interesting As Fuck Reddit Community—repels mustard? It seems strange, doesn’t it? It might even seem unnatural.

What’s going on in this gif?

The bread was treated with a superhydrophobic coating—a material that repels water and other liquids.

How? The material creates surface contact angles greater than 150 degrees, causing liquid to “slide off the coated surface in a surreal-like way,” according to Arizona State University’s Center for Nanotechnology in Society.

This technology can have a bunch of uses. Think about it. Eating food can be easier! You can make a superhydrophobic ketchup bottle in which the condiment just slides right out.

Or, for more important uses, you can create airplane wings that block the formation of ice. And MIT scientists say that superhydrophobic surfaces can make power plants run more efficiently.

One company even created superhydrophobic sneakers.

And in a 2012 PLOS One study, researchers were actually able to cut a water droplet using a superhydrophobic knife.

Isn’t science amazing?

While this may seem like advanced technology, hydrophobic surfaces are also actually found in nature. Lotus leaves and butterfly wings repel water, according to a study published in the Journal of Colloid and Interface Science.

And in the deserts of Africa, stenocara beetles have wings that are covered in hydrophobic troughs that “funnel water towards the beetle’s mouth.”

According to MIT technologists, there are two ways to create a hydrophobic surface. Extreme Tech explains:

“You either coat it with some kind of wax (oil, grease, or some other special, hydrophobic substance); or you use nanoengineering to create a special, nanopatterned textured surface. These nanopatterns, which are hydrophobic, take the form of little bumps or posts that are around 10 micrometers across.”

The biggest question, however, is how we can use superhydrophobic coating to make our lives more easier? One Redditor has an idea:
