Hydroglyphics: Demonstration of Selective Wetting on Hydrophilic and Hydrophobic Surfaces
Kim, Philseok; Alvarenga, Jack; Aizenberg, Joanna; Sleeper, Raymond S.
Journal of Chemical Education, v90 n5 p625-628 May 2013
A visual demonstration of the difference between hydrophilic and hydrophobic surfaces has been developed. It involves placing a shadow mask on an optically clear hydrophobic plastic dish, corona treating the surface with a modified Tesla coil, removing the shadow mask, and visualizing the otherwise invisible message or pattern by applying water, thus entitled as hydroglyphics. (Contains 4 figures.)
