The Big Kerplop!: The Original Adventure of the Mad Scientists' Club by Bertrand R. Brinley, Charles Greer

5.0

I liked it. They were fishing one day and they heard this big sound and it turned out to be a bomb. It took until the end of the book to get it out. Nobody was allowed on the lake and they snuck out on the lake to dive for the bomb. Then they found the bomb. But nobody would believe them. So it took til they had a weather balloon and it showed exactly where the spot of the weather balloon was.
