Google is now using drones to deliver. Items like espresso, golf equipment, and Gelato are all flying to people's doors.

Drone delivery company 'Wing' is owned by Google's parent company. The high-tech service is already delivering orders to about 100 households in Australia.

Wing has been making trial runs in the area for a year, but Australian aviation authorities only recently gave formal approval. Deliveries are expected to gradually expand in the coming months. Drone deliveries in the U.S. have been more limited as companies wait on regulations.
