Would you please provide a summary of Chapters 7 and 8 of Twenty-One Balloons? Thanks!
In Chapter 7, the Professor tells his audience what the citizens of Krakatoa do with all of their spare time. Aside from their assignment of feeding the people of the island on a rotating basis, they really have nothing to do each day once their dwellings have been constructed. As it turns out, the Krakatoans occupy their time in a variety of ways. First of all, they do not ascribe to the adage that "busy hands are kept out of mischief", and are not afraid to relax. Also, since each family has been chosen because they have unique talents and interests, they spend a lot of time making improvements on each others' houses, adding innovative inventions such as an automatic bed-changer/sheet-washer, and elevator beds on which one can sleep out under the stars.
In Chapter 8, the Professor describes an invention the children of the island have created themselves for their own amusement. It is a balloon merry-go-round, which consists of a wheel of hot-air balloons, under each of which is a boat. The children get into the boats and take the Professor for a ride on the merry-go-round, which flies up in the air as it spins, transporting the riders over the mountains and to the sea. Over the sea, the balloons are deflated, and the contraption lands softly. The children then fold up the balloons carefully and sail back to the island on the boats, which are in fact quite seaworthy.
