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。
