Small solar cells provide electricity to miniature engines, which in turn propel the models presented here: a grasshopper, a car, a crab and a frog. An experiment on a wonderful topical issue, contained in objects just a few centimetres long, to be assembled first: the assembling work also helps you understand the secrets of this technology. To make them work you obviously need to expose them to the sun: the shadow of your hand will be enough to stop them
