When I put down the pen, as it happens has one flake paper to be on the side, adhered with the pen at a draught, I was stupefied, a unit of length 2 bonze -- feel do not wear brains, how is this to return a responsibility after all? Then, I tried a few times continuously, small scrip was stuck to go up by the pen, I think: does it also have the function that can you suck iron like magnet? My suddenly be enlightened, the teacher has said: Want a plastic stuff to chafe on the head only, can arise electrostatic, so my small scrip can be adhered by the pen.

Original, there is science everywhere in the life, want us to observe seriously only, try hard to explore, can discover a lot of secret!

几天前,当我写业务的时候遇到了一个难题,我努力思考,用笔在头上刷会涂掉,非常想知道正确的答案。当我放下笔的时候,恰好有一张纸在旁边,一下子就粘上了笔,我呆若木鸡,一单位长度的2棒子——感觉不穿脑筋,这到底是怎么回事?然后,我连续试了几次,小纸条被钢笔卡住了,我想:它还有像磁铁一样吸铁的功能吗?我恍然大悟,老师说:只要一个塑料东西擦在头上,就会产生静电,所以我的小纸条可以被钢笔粘住。

原来,生活中到处都有科学,只要我们认真观察,努力探索,就能发现很多秘密!
