Gunpowder (huo yao) is another ancient Chinese invention. It was invented by accident. More than 1000 years ago people experimenting in a pharmacy made the discovery. They found that if sulphur, charcoal and potassium nitrate were mixed together with a certain proportion, the mixture would explode. Gunpowder changed the style of wars. The steel age ended and gunpowder-based weapons are now widely used. More than 600 years ago primitive guns were used in China. Cannon balls were propelled by the thrust of the huo yao explosion. Now, huo yao is also widely used in fireworks. The splendid fireworks at the Beijing Olympic Games garnered wide acclaim and admiration from the audience.

火药是中国的另一项古老发明，它的发明很偶然。1000多年前，人们在尝试制造各种药物的过程中偶然发现，把硫磺、硝石、木炭以一定比例混合，就可以生产出火药。火药改变了战争的形式，冷兵器时代结束，火药武器被广泛应用。600多年前，中国便有了原始的火炮，利用火药燃烧产生的推力发射炮弹。如今，火药也广泛应用于烟花。北京奥运会上绚烂的烟花赢得了观众的广泛赞誉和钦佩。
