While there's plenty of discoveries that no doubt wouldn't have been possible without coffee, few have been as directly influenced as this latest fit of inspiration from Ivan Vakarelski of the Institute of Chemical and Engineering Sciences in Singapore, who apparently saw the future of TV screens in a coffee stain. More specifically, he was intrigued by the way a coffee spill dried into a circular stain, which, as New Scientist notes, is effectively caused by coffee granules being "assembled" by the varying evaporation and convection rates in the fluid. That process, Vakarelski thought, could be replicated artificially to create a better coatin
