The solution: put the ink directly in the water, according to co-author Thomas Palberg of Johannes Gutenberg Universitaet Mainz, and use a microbead made of ion-exchange material as a pen

Human writing and drawing dates back at least 30,000 years and incorporates traditional techniques such as carving, engraving, and printing/writing with ink, as well as more novel methods such as electron lithography. Now a team of German physicists has figured out a unique method for writing in water and other fluid substrates, according to a recent paper published in the journal Small.
