Diana loves beaches. But she often sees the sand covered with plastic bottles.

“This needs to be changed.” Diana said. So she studied online. After some tries, she created a new kind of water bottle. People can actually eat it! It can be broken down without polluting the environment. Diana said the bottle felt like a soft candy and tasted a bit sweet.

In the future, Diana will do more tests to make the water bottle stronger and bigger. She wants her water bottles to be used during marathons (马拉松). When runners stop for water, they can get a bottle of water, drink the water and either eat or throw the bottle.

Getting a pie from the sky is becoming a reality in the city as online delivery platform Meituan has been allowed to start drone delivery service(无人机送餐服务), Shenzhen Evening News reported.

At Galaxy World in Longgang District, a reporter from the newspaper watched how a meal has been delivered by the drone on Thursday. The drone slowly landed and a door above the Meituan Intelligent Dining Cabinet(储藏柜) opened slowly, where the drone put the meal box inside the cabinet.

“It takes about 15 minutes to place the order and receive the meal. A lot of people have tried the drone delivery service here,” said a woman who just took her meal box out from the cabinet.

During the year 2022, food and drinks such as noodles, fruits, coffee and milk tea and even flowers have been delivered through Meituan’s drone delivery system, the report said.

The company said that as of last year, it had completed over 100,000 drone deliveries. Meituan started to explore drone delivery service in 2017 and started the try in early 2021. The service has an average delivery time of 12 minutes, which is less than traditional delivery methods, according to the company.

There are only a few cities in the world with the advantages of drone delivery service, and Shenzhen is taking the lead in China, according to the report. However, there are still some problems with this kind of service.
