A time capsule is a container filled with things that show what life was like at a particular time. It is stored for a fixed period-for example, 100 years-and then opened a gain. Time capsules are often put into the walls of new buildings, or they may be buried in the ground. They usually contain photos, letters, newspapers, and objects from everyday life. A carefully made time capsule preserves a living record of history and gives people a voice into the future
According to the International Time Capsule Society,there are about 10,000 time capsules in the world. However, many of them have been lost or forgotten. For example, in Blackpool, Lancashire, England, a time capsule was built in the late 1800s. Unfortunately, no one recorded the exact location. When people searched for it 100 years later, they were unable to find it. The International Time Capsule Society now keeps an official record of time capsules around the world to avoid problems like this in the future.
