For 1st time, scientists write words in liquid water

0 29

Scientists have discovered a way to write directly into liquid water, creating clear and long-lasting patterns which float below the surface of the fluid.

In the new study, published Aug. 21 in the journal Nano Micro Small, Benno Liebchen and colleagues at the Technical University of Darmstadt and Johnannes Gutenberg University in Germany have developed a method to create long-lasting writing inside of a liquid. The water-writing  relies on a chemical process called diffusioosmosis — a spontaneous movement of different types of particles, caused by a difference in concentration within a liquid mixture.
