Description

5ef1bf157597a99b9cfac8c869d02a
材料:瓶子、吸管、变色粉
【产品名称】  吹气变色

【主要成分】  花色素

【原理】 植物因为含有花色素而呈现五颜六色、多姿多彩,花色素因为

            酸、碱性的不同而发生颜色变化,吹气的主要成分是二氧化碳,

            在水中显弱酸性,因为水溶液pH发生改变导致花色素颜色消失。

【规格】  0.5g

【保质期】  2年

【注意事项】吹气时请佩戴护目镜,如液体不慎溅入眼睛,请立即用水冲洗。如果没有护目镜,可以用杯盖或者一张纸盖住瓶口或水杯口,吸管从纸上穿洞插入杯中,这样可以防止吹气时液体飞溅出来。

【使用方法】

                 1, 往塑料瓶中加80ml水(大约小半瓶水,如果水

                     加多了,颜色会比较浅)。

                 2,倒入吹气变色粉,搅拌溶解。

                 3,用吸管往水里吹气,大约一分钟后颜色消失。
