A visual demonstration showing the physical properties of hydrophobic and hydrophilic surfaces is described. This demonstration utilizes unique aqua-sheets that are fabricated using plasma enhanced chemical vapor deposition (PECVD) to give areas of high water contact angle (hydrophobic) and areas of low water contact angle (hydrophilic). The hidden pattern or message can be made visible by applying food dye-stained water to the sheets, resulting in aqua-art.
