Mocky Roundtin has one of those cookery book holders. It is a very snazzy one that keeps the recipe book open at the right page, and has a perspex cover to keep the pages clean. Unfortunately it was difficult to read the book, as it kept wobbing about after he had been using the food mixer. He decided to try and fix the cookery book holder. It did not take long for him to discover the reason for the wobbliness: it had a rocky mounting.
