"Two enterprising mice, Ginger and Mac, are on a mission to bring home an especially aromatic vanilla cupcake with pink buttercream frosting. They have discovered that the amount of work you need to put into a job can almost always be decreased by using one of six simple machines: a lever, a wheel and axle, a pulley, an inclined plane, a wedge or a screw. Simple machines have only one or two parts that can usually be found around the house - and they can make life a lot easier! Ginger and Mac make use of all six simple machines and manage to overcome all obstacles in their mission to secure a delicious frosted treat."-- Provided by publisher.
