Time capsules

I think time capsules are a little popular among elementary school in Japan .
It's very interesting , because that makes them remember about childhood . They tend to put picture , letter to themselves time , and toy in time capsules .
Actually , I've never used time capsules , but If I used time capsules , I would put in these things .

1. I want to put wine which made of 2009 into time capsule .
2. I want to put paper which I wrote about prediction .
3. I want to put picture that is with my family , friend , and girlfriend .

What do you want put into time capsules ?
