1.导体制作:用直径1毫米左右的铜丝或镀锌铁丝,穿入塑料瓶盖中心孔内(如图1),上端弯一圆环,中间凸出二个半圆环,下端弯两个位置相对形状相同的等腰三角形环。弯制时,导体两端要锉圆且弯回贴着导体,以防尖端放电。2.直角铝箔制作:将包装卷烟铝箔放入水中浸泡,刷去纸面,裁剪成图2中(a)所示形状,再折成直角,弯好挂钩,如图2 1 conductor production: with a diameter of about 1 mm copper wire or galvanized wire, into the center hole in the plastic cap (Figure 1), the upper end of a curved ring, the middle protruding two semi-circular ring, the lower bend two An isosceles triangle ring with the same shape and position. Bending, the conductor at both ends of the file to be rounded and bent back to the conductor, to prevent the tip discharge. 2. Right-angle aluminum foil production: The packaging of aluminum foil into the water soaked, brush to the paper, cut into the shape shown in Figure 2 (a), and then folded into a right angle, bend the hook, as shown in Figure 2
