Marble (toy) in Codd-neck bottles, which were often collected for play. In the early twentieth century, small balls of stone, identified by archaeologists as marbles, were found on excavation near Mohenjo-daro. Marbles are often mentioned in Roman literature, as in Ovid's poem "Nux" (which mentions playing the game with walnuts), and there are many examples of marbles from excavations of sites associated with Chaldeans of Mesopotamia and ancient Egypt. They were commonly made of clay, stone or glass. Marbles arrived in Britain, imported from the Low Countries, during the medieval era. In 1503 the town council of Nuremberg, Germany, limited the playing
Liquid marbles at the hexane/water interface, providing that the hexane phase is not depleted by vaporization. The interfacial water marbles can also realize a series of stimuli-responsive motions by integrating the functional materials into the surface coating layer. Due to their uniqueness in both form and behavior, the interfacial water marbles are speculated to have remarkable applications in microfluidics, microreactors and mass-transport. Liquid marbles Liquid marbles are non-stick droplets (normally aqueous) wrapped by micro- or nano-metrically scaled hydrophobic, colloidal particles (Teflon, polyethylene, lycopodium powder, carbon black, etc.); representing a platform for a diversity of chemical and biological applications. Liquid marbles are also
