材料:竹片(或木片)、竹筷、竹筒、细绳。制作:取竹片或木片1块,用小刀削成螺旋桨形状,并在中心处钻1小孔,装上1根竹筷,作为支杆。这样,竹蜻蜒就做好。用两手掌夹住竹蜻蜒的支杆,用力一搓,迫使竹蜻蜓高速旋转。只要旋转方向对头,它就会飞起,上升到约4米高的空中(注意:手臂要向前伸直,不要让竹蜻蜒打到自己的头和眼睛;如果旋转方向反了,竹蜻蜒会向下飞,打着自己的手)。
Materials: Bamboo (or wood chips), bamboo chopsticks, bamboo tube, string. Production: Take a piece of bamboo or wood and use a knife to cut into a propeller shape. Drill a hole in the center and put a bamboo chopstick as a support rod. In this way, bamboo rafts will do well. Hold the poles of the bamboo poles with both hands and force them to force the bamboo poles to rotate at high speed. As soon as it turns in the opposite direction, it will fly and rise to a height of about 4 meters. (Note: The arm must be straight forward. Do not let the bamboo pole hit your head and eyes; if the direction of rotation is reversed, The owl will fly down and hit his own hand.)
