一、制作材料橡皮筋、PVC管、KT板、废旧光盘、大头针、旧圆珠笔芯、剪刀、双面胶、彩色卡纸、美工刀、透明胶布等。二、制作步骤首先制作小车的动力装置,用橡皮筋作动力可以利用它的拉伸力和扭转力两种。橡皮筋的拉伸力爆发力强,但是不能保持持久; First, the production of rubber bands, PVC pipe, KT board, disc disc, pin, old ballpoint pen, scissors, double-sided adhesive, color cardboard, utility knife, transparent tape and so on. Second, the production steps First make the car’s power plant, rubber band for power can use its tensile strength and torsional force of two. Tensile strength of rubber band explosion strong, but can not be sustained;
