It’s about a group of kids that build a flying raft, for lack of a better term, and refuse to descend back to the ground until their parents conform to their wishes. I think there might have been some sort of a social moral involved.
It has been many years since I read this, it’s probably considered a book for pre-teens IIRC.
Thanks in advance to the person that nails it.
