3It wasn't the diamond as big as the Ritz but it was a pretty big chunk of ice and it got the precocious pranksters of The Mad Scientists Club entwined in an international intrigue that only the intrepid investigators of Interpol could unravel. Take the seven young mad scientists of Mammoth Falls, stick them in an antiquated blimp bound for the Austrian Alps, along with two hep young college girls and a zany professor of mysterious Rumanian origins, and you have the makings of a high-flying fun fest that could only come from the author of The Mad Scientists Club and The Big Kerplop! If you're not already a fan of superbrain Henry Mulligan, dinky Dinky Poore, fat Freddy Muldoon, and the other unpredictable troublemakers that populate this series of mad, mad adventure stories, you will be, once you read the Big Chunk of Ice.
