Hot air is lighter than cold air. So balloons with hot air can rise into the sky. Hot air balloons have burners to keep the air hot. They also have baskets for people to stand in. In Africa, peope can watch wild animals from hot air balloons. These trips are called balloon safaris.

热空气比冷空气轻，所以装有热空气的气球能飞到天上。热气球利用装着的燃烧器保持球内气体的热度。也可以在热气球的底部撞上篮子，供人站立。在非洲，人们可以从热气球上看野生动物。这种旅行被称为气球游猎。
