(Phys.org)—A team of researchers with Universit Grenoble Alpes in France has discovered that there are differences in patterns created in tiny particles immersed in water over a vibrating drum head,than in dry sand particles dropped on a metal plate and vibrated. In their paper published in Physical Review Letters, the researchers report their experiments and the differences they found between the submerged particles, and the patterns that developed and the mechanisms behind them.
