Scott Corbett’s Trick Books centered around the adventures (and misadventures) of a young boy named Kerby Maxwell, his friend Fenton, and his dog Waldo.
Kerby stops to help an eccentric old woman with her heel stuck in a drainage grating. Her name is Mrs. Graymalkin, and she is so grateful to Kerby for saving her shoe that she later rewards him with a mysterious old chemistry set that belonged to her son when he was a boy. But this is no ordinary chemistry set- when the mysterious chemicals are mixed to Mrs. Graymalkin’s instructions, they have the powers to create many wonderful, exciting effects!
Trouble hitting a home run at the game? A drop of a special mixture onto the ball will solve that! Your dog run away? A special concoction will make his whereabouts appear in the beaker! And so on and on. For every problem, there’s a potion to fix it!
Mrs. Graymalkin’s potions create such magical results, Kerby believes she is a witch, whereas levelheaded Fenton believes she is a genius scientist who happens to be extremely eccentric!
And who knows…? Maybe they’re BOTH right!

The last and one of the best in the series!

Kerby’s cousin is back, and they try another experiment which leaves all of them smelling like the type of food they hate the most. The terrible news is that the only way to get RID of the smell is to EAT the very dishes they despise! But where will they find a place to get all the dinners before their parents come home? ( )
