The Twenty-One Balloons is about a schoolteacher named Professor William Waterman Sherman. Professor Sherman lives in San Francisco. The year is 1883. Mr. Sherman is bored, and decides to quit teaching so he can live in a hot air balloon for a whole year.
He had a humongous hot air balloon made, and a giant bamboo basket for him to live in. Unfortunately, three weeks into his voyage, something happens and he is stranded on an “uninhabitable” island. This island is the island of Krakotoa, which is between the islands of Sumatra and Java, islands of Indonesia. Krakotoa is said to be uninhabited because of an active volcano, which had erupted some years before.
It turns out that Krakatoa is actualy inhabited, by 20 families consisting of 1 father, 1 mother, 1 son, and 1 daughter. They are all very wealthy, because there are diamond mines with diamonds the size of base balls in abundance. The inhabitants of Krakatoa run restaurants, too.
