Google’s delivery drones
Google wants to expand into the real world. Google works on self-driving cars, solar-power balloons, and now also on drones. These drones will deliver things.
The drones look like small airplanes. They can fly without people’s help. They can bring you many things. However, Google is still working on this project. It will take years.
Difficult words: expand (become bigger), drone (machine which can fly without the pilot), deliver (to bring something).
