自制烟花可能有致命危险。千万不可尝试自制设备，不要购买或使用被大肆宣传用来制作烟花的工具。化学火药在被混合并装入的时候是非常危险的，可能对人造成严重伤亡。请将烟花的制作留给专业人士。
Homemade fireworks can be deadly. Never attempt to make your own devices and do not purchase or use any kits that are advertised for making fireworks. Mixing and loading chemical powders is very dangerous and can kill or seriously injure you. Leave the making of fireworks to the experts.
