Two clever (and hilarious!) mice use physics to retrieve a tasty treat. Ginger and Mac are pros at snatching up delicious tidbits and bringing them back to their mousehole to eat. Today, though, their mission is complicated. Their target is a vanilla cupcake with buttercream frosting. Only, it's (a) too big for them to carry, (b) within leaping distance of the resident cat and dog and (c) under a heavy glass cake dome. Luckily, these mice love a challenge. Ginger is sure they can use simple machines to get the job done. But is she right? Operation Cupcake is both a laugh-out-loud adventure and a "paws-on" introduction to simple machines. What could be better for learning science?
