爆米花
不是所有的玉米都能爆开。只有当一粒玉米种子里含有14%的水分时才能爆开。少于14%水分的玉米不能爆开。当你加热一粒玉米种子时，种子里的水分使玉米爆开，这时会发出“砰砰”的声音，所以我们把它称为爆米花。
很久以前美洲印第安人就开始爆爆米花。他们知道一共有三种玉米，分别是可以食用的甜玉米、给动物吃的玉米和爆爆米花的玉米。当第一批定居者，也就是清教徒于1620年来到美洲后，印第安人把玉米介绍给了他们。一年后，新移民举行了第一次感恩节，他们邀请了印第安人，印第安人带来了食物，其中有一个印第安人带来了爆米花！
从那以后，美国人一直在家里爆爆米花。1945年，一种新的机器改变了爆米花的历史。
这种电动机器可以在家庭以外的地方爆爆米花。很快电影院里开始出售爆米花赚钱。电影院里的爆米花越来越受欢迎。现在美国人仍旧保持着在电影院里吃爆米花的传统。
