Spray-on NeverWet street art appears after it rains

Spraying this liquid-repelling coating on a stencil provides a unique way for people to share messages that become visible after the design comes in contact with water.

Some creative thinkers discovered that NeverWet -- a superhydrophobic spray-on coating that makes liquid roll off any surface -- works wonderfully as a way to create secret sidewalk art that can only be activated by water.

If you want to create some sneaky street art, then find a concrete sidewalk (or driveway), lay down a stencil, and spray it with NeverWet. After the NeverWet coating dries and rainfall comes, voila! The stenciled pattern stays dry and becomes highly visible on the soaked sidewalk. The element of surprise may vary on surfaces aside from concrete, as NeverWet dries with a somewhat frosted appearance.

The NeverWet stencil method, dreamed up by Home Depot forum users Nathan Sharratt and Dana0814, appears like a 21st-century version of invisible ink.

NeverWet stenciling could prove an innovative way for homes and businesses to decorate their pathways after it rains -- e.g. a business could offer customers a special rainy day discount, or homeowners could apply their favorite sporting team logo to their driveway without having to worry about the homeowners association freaking out.

Of course, there's also great potential for pranksters to use NeverWet stenciling for heinous messages, so spray wisely.
