How it works
A capsule's journey
1
Write and decorate
Write your letter. Add photos, files or a song, and pick the colour of the seal.
2
Pick a time
An hour from now, next summer or ten years away. You set it to the minute.
3
Seal and send
Once sealed, the capsule can't change. Send the link yourself or have it emailed the moment it opens.
4
The moment it opens
When the time comes, the link opens, the seal breaks and the letter can be read. Until then, nobody can open it.
Riddle lock
If you add a question, the answer is needed even after the opening time. Case and spaces don't matter. With each wrong guess, the hints you wrote appear one by one. We don't know the answer either, so it can't be recovered if forgotten.
Who can see it?
What you write stays private. Only people with the link can read it, and only after it opens. If you show it on the wall, only its name and countdown appear there.
