Deletion of Water retention on mathematical surfaces

Comment: the article essentially rests on a single source, a competition, with two primary sources of mathematical research on water retention models (not on magic squares). This is a typical pattern of sourcing for Original Research (). There is interest here for a mathematical column in New Scientist or Scientific American, perhaps, but not for Wikipedia, at least not until the topic is reviewed in "reliable, independent" secondary sources. Fails Notability
