Lista Mo Sa Tubig (List It Down on Water)

Whenever someone loans money from you and says "ilista mo na lang sa tubig" (just list it down on water), it means that the person asking for the loan has no intentions of paying you simply because... it was listed on water and there's no way for you to go back on that "list".  Well, a lot of people may have had loans with the Japanese professors at Akishima Laboratories and did something about it:  they invented a way to actually write on water!


They do this by encircling a small body of water (1.6 meters in diameter and 30 cm deep -- about the size of a backyard kiddie pool) with wave generators.  The wave generators move up and down in controlled motions to simultaneously produce a number of cylindrical waves that act as pixels. The pixels, which measure 10 cm in diameter and 4 cm in height, are combined to form lines and shapes.

Here's the original source of this piece.
