将吸水能力超强的高分子聚合物聚丙烯酸钠置于三个纸杯期中之一的杯底,用少许水将其湿润之,使聚丙烯酸钠先被附着在杯底,演示此一科学魔术时,先将三个纸杯到过来给大众看,表示三个杯子里面是空的,然后将三个杯子排成一列,两个空杯子在中间及右边,而加有「聚丙烯酸钠」的杯子摆在左边,演示时将少许水倒入右边第一个杯子中,再将第一个杯中之水倒入第二个杯子中,接着将第二个杯中之水倒入第三个杯子中,最后将此三个杯子随意调换其位置,请观众猜猜看水在那一杯中。
Put the super absorbent polymer sodium polyacrylate into the bottom of one of three paper cups and moisten it with a little water so that sodium polyacrylate is first attached to the bottom of the cup. , The first three cups to come to the public to see that the three cups are empty, then the three cups in a row, two empty cups in the middle and right, and add a “sodium polyacrylate” cup On the left, pour a little water into the first cup on the right, pour the water from the first cup into the second, and pour the water from the second into the third cup , And finally the three cups to change its position, please guess the audience guess the water in that cup.
