Take the imagination of bestselling author Gordon Korman, add the hands-on expertise of the popular Mad Science group and eureka! A hilarious new science fiction series!

Taste bud tricks. Artificial mucus. Skeleton models made out of marshmallows. Mr. Flask has his sixth graders studying the science of the human body. The Professor eagerly watches their experiments and then comes up with one of his own: the superpowered muscle-regenerating body rub. Too bad he couldn't keep that huge vat of goo from flooding the gym!
The latest title in the ongoing series about science facts, fun, and the ongoing feud between the von Offels and the Flasks.
