在阴雨绵绵无法外出玩耍时,我们可以用家里容易找到的糖果盒、糕点盒或者奶粉罐等圆柱形的容器来制作有趣的空中动画片。物体在快速运动时,当人眼所看到的影像消失后,人眼仍能继续保留其影像0.1～0.4秒,这种现象被称为视觉暂留现象。而“空中动画片”就是利用这个原理制作的。 In the rainy days can not go out to play, we can easily find the home with candy boxes, cakes boxes or milk cans and other cylindrical containers to make funny aerial animation. When the object moves fast, the human eye can still retain its image for 0.1 ~ 0.4 seconds after the image seen by the human eye disappears. This phenomenon is called the phenomenon of persistence of vision. And “Sky Cartoons” is the use of this principle produced.
