    摘要: A coaster with the attributes of a wipe wherein two layers of absorbent material such as paper are separated by spacers. As the condensation collects on the upper absorbent layer, it sags and creates air pockets preventing the wet glass from sticking to the coaster. Through judicious choices in the spacers, the resulting coaster can be as flexible as a paper napkin or can be used for entertainment.

    摘要翻译: 具有擦拭物属性的过山车,其中诸如纸之类的两层吸收材料由间隔物隔开。 当凝结物聚集在上吸收层上时,它会下沉并产生防止湿玻璃贴在过山车上的气穴。 通过在间隔件中的明智选择,所得到的过山车可以像纸巾一样柔软,或者可以用于娱乐。
