    Earlier this year in Norway, people buried a steel bottle with plant seeds, a wristwatch and rock samples (样本) in it. Why did they do this? They were making a time capsule(时间胶囊).

Time capsules are small collections of goods or information that are stored somewhere safe. They can be opened by people many years later, giving future people a view of life in the past.

They may contain (包含) newspaper articles, popular music recordings, and photos. Historians can use time capsules to learn more about societies that lived in the past.

One of the earliest time capsules was the Detroit Century Box. On Dec 31st, 1900, the city picked several photos and letters to be placed in a box. The box was then locked until Dec 31st, 2000. The things inside the capsule give us a look at Detroit in the past. There were photos of people and places, as well as letters written by local people. Some of them even gave predictions for the future. One person predicted that Detroit would have a population of 4 million by 2000. But in fact, the city’s population was about 951,000 that year.

Humans have even sent time capsules into space! The US sent two capsules into space on the Voyager spacecraft (旅行者号航天器) in 1977. They are called the Voyager Golden Records. They contain sounds and pictures that show the diversity of human life and culture. For example, they have music by German composer (作曲家) Beethoven and pictures of plants, insects and landscapes (山水风景画). The Voyager spacecraft has traveled far away from our solar system(太阳系). It is hoped that aliens might find the time capsules someday and learn about us.
