A simple airhorn can be constructed by stretching a balloon over the opening of a small container or cup with a tube through the other end (see Figure).

通过把气球套在一个杯子（或者其他的柱状容器）开口上，就可以制作一个号角了。 通过小孔吹气，就能响。

I love looking at the smallest detail, the smallest action - an old balloon lying on the couch, the way someone washes his hair or holds his cup.

我喜欢关注最微小的细节，最微小的行为——沙发上一只破旧的气球，某个人洗头或者拿杯子的方式。

The hype was Macy's balloon-sized for this horse, who was undefeated as a 2-year-old until the Breeders' Cup Juvenile, where he came in second.
