illustration Friday: Invention

     This is another illustration from my latest book, "Haley and the Big Blast," written by A.E. Scotland and illustrated by Yours Truly for Amy Elise Press.
     Haley is a young inventor who's constant experiments get her into all sorts of trouble.
     In this scene, she noticed the slide didn't "slide" very well - so she added cooking oil - which made it work a little bit too well!
