Invisible graffiti appears only when it rains

22.9.13

Atlanta-based artist Nathan Sharratt had been exploring the idea of rain drawings ever since he saw a video about superhydrophobic coatings over a year ago. Sharratt first tried a single-layer coating spray that repelled water but wasn't strong enough to create a noticeable difference between dry and wet for more than a few minutes in the rain.

When Sharratt heard of the new NeverWet two-layer waterproofing spray system, he revived the rain drawings project and submitted the following artworks, which ended up making top 10 in the contest.
