Google wants to expand into the real world. It works on self-driving cars, solar-powered balloons, and also delivery drones. The drones will rival Amazon’s services.
The drones look like little airplanes, and they will be able to fly on their own. They can get you anything from sweets to medicine.
The project will take years of development.
Difficult words: expand (become larger), drone (unmanned aircraft), development (work).
