This is a story about a family of three who get into an accident while traveling and end up on a deserted island. Rather than talking about how to survive when actually arriving on a deserted island, it teaches various scientific common sense by assuming such an event.

In each chapter, stories about various situations are comically compiled into cartoons, and scientific common sense related to the topic is organized one by one. You can easily learn common sense that cannot be learned from textbooks, such as how to obtain water, measure direction, obtain salt, and measure the weather.
