首先我们要准备以下材料:一个大水杯、一个小水杯还有一个U型吸管。准备就绪后,我们先要把大水杯里面装满水,小杯子还是空的状态,然后要把U型吸管剪成一长一短的样子。接着我们把U型吸管放入大杯子水中,其中U型吸管的长处要在水中低于吸管的短处,然后我们慢慢地等U型吸管里面全部装满水。之后我们缓缓地拿出吸管用食指抵住U型吸管长的那处吸管孔,我试了很多次都没有成功,有点灰心,后来妈妈鼓励我,让我试了一次又一次,终于成功把U型吸管倒过来放入两个杯中,其中U型吸管长的那段放入充满水的大杯中,低的那段同时放入空的小杯中。最后我把手松开,这时奇迹出现了,只见大杯中的水通过U型吸管慢慢都流到了空的小杯子中。我跟妈妈看得目瞪口呆,真是一项好玩的小实验。
