We tried to make the book that will attract more kid to read by making fun story with science in there and attractive pictures. The book is include two languages witch are Khmer and English. I and Visal are making the book that is about buoyancy. Our book tittle call Sink or Float and in our book we have funny characters like Mr. Coconut, Mr. Rock and Mr. Ball. We decide to use the as our characters name because the kid in Cambodia they like to play the ball, so it will attract more kid to read our book.
