走马灯:又名马骑灯,是中国传统玩具之一,灯笼的一种,常见于元宵、中秋等节日。现介绍的是一种简易型的走马灯——会旋转的纸环。材料:剪刀、正方形卡纸、铁丝(一头磨圆)、蜡烛、母子扣、圆规、蜡笔(或水彩笔)步骤:1.用圆规在白色卡纸上画相等距离的同心圆,只画圆的上半部分就可以了,像彩虹一样。2.画下半部分的同心圆,圆心选在最小圆半径的中点上,半径取到最小圆圆周的一点上,画圆。这样就使上半部分两个相邻的同心圆通过下半部分的同心圆,把它们连接起来了,最后回到原来的圆心上,以最大圆的圆周半径为半径画圆。
Lantern: also known as horse riding lamp, is one of China’s traditional toys, a lantern, common in the Lantern Festival, Mid-Autumn Festival. Now introduced is a simple type of lamp - will rotate the paper ring.

Draw a circle with the same distance on the white cardboard concentric circles, The upper part is ok, like a rainbow. 2. Draw the lower part of the concentric circles, the center of the circle selected at the midpoint of the minimum radius of the circle, the radius of the circle to get the smallest point on the circle. So that the upper part of the two adjacent concentric circles through the lower part of the concentric circle, connect them, and finally back to the original center of the circle with the maximum radius of the circle radius of the circle.
