小时候同学们都吃过棉花糖吧?当你们拿着像棉花似的糖,享受它的美味时,你们想没想过它是怎么做出来的,用了什么方法才能把糖做得像棉花一样呢?其实,棉花糖是利用“离心现象”做成的,将糖粒放到机器内侧的圆筒里加热熔化,再让机器高速旋转,熔化的糖汁就会在离心力的作用下,从内侧圆筒筒壁上的小孔飞散出去,降温冷却后,重新凝结成蓬松的糖丝,像一团纤细雪白的棉花。右图就为大家演示了这种离心现象,中间有一个转动机构,上面连接了两个上下都固定的装满水的密闭圆筒。一个圆筒里放了一个沉在水底
When I was young, my classmates ate marshmallows. When you took the sugar like cotton and enjoyed its delicacies, you never dreamed how it was made. What method did you use to make sugar as cotton? In fact, marshmallow is the use of “centrifugal phenomenon ” made of the sugar particles into the cylinder inside the machine heated to melt, let the machine rotate at high speed, the melting of the juice will be in the role of centrifugal force, From the inside of the cylinder wall hole flew out, cool down after cooling, re-condensed into fluffy sugar, like a group of slender white cotton. The picture to the right shows the centrifugal phenomenon, with a rotating mechanism in the middle, to which are attached two closed cylinders filled with water that are fixed up and down. A cylinder put a sink in the water
