Marble (toy) of marble games to a meadow outside the town. It is unknown where marbles were first manufactured, but the "original" marbles were designated "made in Germany". The game has become popular throughout the US and other countries. Ceramic marbles entered inexpensive mass production in the 1870s. A German glassblower invented marble scissors, a device for making marbles, in 1846. The first mass-produced toy marbles (clay) made in the US were made in Akron, Ohio, by S. C. Dyke, in the early 1890s. Some of the first US-produced glass marbles were also made in Akron, by James Harvey Leighton. In 1903,
Liquid marbles at the solid-air interface, the interfacial liquid marbles are constructed on the hexane/water interface using water droplets with a surface coating composed of nanoscale materials with special wettability (Figure 2). To realize interfacial water marbles at hexane/water interface, the individual particle size of the surface coating layer should be as small as possible, so that the contact line between the particles and the water reservoir can be minimized; special wettability with mixed hydrophobicity and hydrophilicity is also preferred for the interfacial water marble formation. The interfacial water marble can be fabricated by firstly coating a water droplet with nanomaterials with
