Last week's winners - Time-capsule challenge
We had suggestions for everything from mobile phones, music and teddy bears to science text books - and then there were some great ideas about how to protect the contents for 1000 years. Plastic featured heavily here - it's annoying when it is thrown away and damages the environment and wildlife, but when you are trying to keep something safe for a very long time then a container that doesn't rot or degrade is really useful.
The winner this week is Georgia, age 8, who wrote a very moving "letter to the future" explaining all about what life is like in 2020, and how much she is missing her friends at the moment. Well done Georgia!
