今天我在《趣味科学》上看到这样一段话:让报纸带电,不用胶水、胶布等黏合的东西,报纸就能贴在墙上掉不下来。我心想,这怎么可能呢?百闻不如一见,百见不如一干。我决定照着方法做这个实验。材料很简单,只需要一根铅笔和一张报纸。我找出一张废报纸,然后展开,平铺在墙上,最后用铅笔的侧面迅速地在报纸上摩擦了几下,我慢慢松开手,退后一步, Today, I read this passage in “Fun Science”: Let the newspaper live without newspapers, glues, tapes, etc. The newspaper can be attached to the wall without falling. I thought, how is this possible? I decided to do this experiment according to the method. The material is very simple, only need a pencil and a newspaper. I found a waste newspaper, and then unfold, tiled on the wall, and finally rubbed a few times with the pencil on the side of the newspaper. I slowly released my hand and took a step back.
