材料:一只米酒瓶(底部没有图案、数字),一只普通废灯泡,一台学生电源,一段300毫米的镍铬丝,一把锉刀,一块磨石,二段绝缘导线。 制作方法:把电热丝连好两段导线,接在学生电源上,先在电灯泡的颈部适当位置,用纸围好,沿纸边小心地用锉刀刻两段刻痕,把电热丝绕在刻痕处,通以12～15伏左右的电流,经过2分钟左右,切断电流,除去电热丝,迅速把该灯泡浸入冷水中,裂口比较整齐,不光滑的地方可以蘸水放在磨石上磨平。(图1) 利用同样的方法,在距离米酒瓶底面约2厘米高的圆周处,切割好“水晶球”底座(图2)。
Materials: One rice wine bottle (no pattern, number on the bottom), a normal waste bulb, a student power supply, a piece of 300mm nichrome wire, a file, a grindstone and two insulated wires. Production method: The wire with good wire, connected to the student power supply, the first place in the neck of the light bulb, a good paper, along the paper edge carefully carved two scored, the heating wire around Scotch marks, through 12 to 15 volts of current, after about 2 minutes, cut off the current, remove the heating wire, the bulb immersed in cold water quickly, relatively neat gap, not smooth place can be placed on the mill on the ground water mill level. (Figure 1) Using the same method, cut the “crystal ball” base (Figure 2) at a circle approximately 2 cm high from the bottom of the rice wine bottle.
