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
Wooden toy train Wooden toy train Wooden toy trains are toy trains that run on a wooden track system with grooves to guide the wheels of the rolling stock. While the trains, tracks and scenery accessories are made mainly of wood, the engines and cars connect to each other using metal hooks or small magnets, and some use plastic wheels mounted on metal axles. Some trains are made to resemble anthropomorphical, fictional, and prototypical railroad equipment. Marshal H. Larrabee II founded the Skaneateles Handicrafters in 1936. This toy company made wooden toy trains and wooden tracks. The gauge was very similar to that
