Corbett, Scott. Lemonade Trick, The. 1960. Archive.org.

Was it really magic? When a mysterious old lady gave Kerby the magic chemistry set, strange things began to happen. One sip from a special vial and Kerby felt terribly good, frighteningly good. In fact, Kerby felt so good that he couldn't keep himself from mowing the lawn, cleaning the cellar, the garage, and all manner of good deeds.

Not only Kerby was affected by the magic of the little vial. It was irresistible to anyone who smelled it. Even Waldo, his dog, was compelled to fill in the holes he dug and be polite to the neighbor's cat. And when Kerby added the mystery liquid to a pitcher of lemonade, the result was sensational. The town bully turned angelic, the Sunday school pageant became a riot, and the effects of the lemonade trick on the nicest boy in town were even more astounding.

I enjoyed reading a Scott Corbett book so much I had the urge to read another one. I decided on the first of the Kerby “Trick” series of books that he wrote. This series is what first made me aware of Scott Corbett and made him my favorite author.
