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 shows, by developing a method of mass production using a copper plate printing process. Popular imagery on the lanterns included royalty, flora and fauna, and geographical/man-made structures from around the world. The modern zoetrope was invented in 1833 by British mathematician William George Horner and was popularized in the 1860s. Wood and porcelain dolls in miniature doll houses were popular with middle class girls, while boys played with marbles and toy trains. The golden age of toy development was at the turn of the 20th century. Real wages were rising steadily in the Western world, allowing even working-class families to
