Liquid marbles Liquid marbles provide a new approach to transport liquid mass on the solid surface, which sufficiently transform the inconvenient glass containers into flexible, user-specified hydrophobic coating composed of powders of hydrophobic materials. Since then, the applications of liquid marbles in no-loss mass transport, microfluidics and microreactors have been extensively investigated. However, liquid marbles only reflect the water behavior at the solid-air interface, while there is no report on the water behavior at the liquid-liquid interface, as a result of the so-called coalescence cascade phenomenon. When a water droplet is in contact with a water reservoir, it will quickly pinch off
Toy train trains made of tinplate weren't scale at all, made to unrealistic, whimsical proportions similar in length to modern HO scale, but anywhere from one and a half to two times as wide and tall. Some adult fans of toy trains operate their trains, while others only collect. Some toy train layouts are accessorized with scale models in an attempt to be as realistic as possible, while others are accessorized with toy buildings, cars, and figures. Some hobbyists will only buy accessories that were manufactured by the same company who made their trains. This practice is most common among fans of
