SealdayFamily time capsule ideas
A family time capsule works best when every age group gets a task: children draw or guess, parents write, grandparents tell a story. Seal answers at a holiday or reunion, open them at the next one, and keep the questions light enough that a six-year-old and a seventy-year-old both finish.

When should a family open its capsule?
At the next gathering of the same group. For most families that means next year's holiday dinner, summer reunion or birthday party. The date works because everyone is in the room already and the memory of last year is a short list of things.
Longer capsules suit milestones: a grandparent's eightieth birthday, a child's graduation, a move. For these, pick a day that the family will mark anyway.
What can each age group do?
| Who | Task | Example |
|---|---|---|
| Ages 4 to 7 | Draw or say a guess aloud | What will our dog look like next year? |
| Ages 8 to 12 | Short predictions | Who will be tallest at the next dinner? |
| Teens | A prediction and a photo | The song everyone will be playing |
| Parents | A letter and guesses | Where we will be living, what we will cook |
| Grandparents | A story, recorded | A recipe and where it came from |
What questions work for the whole table?
Keep the questions kind. Avoid health, money and anyone's private matters, a rule Sealday's own starter questions follow.
- What dish will we make that we have not made before?
- Who will be the first to arrive next year?
- What tradition should we start, and what should we retire?
- Which family member will surprise us?
- What will the family group chat be named?
- Which trip will we take together?
- What will the kids have learned?
- What will we be talking about at this table next year?
How do we run it with a Table?
Free Tables hold four people and Plus raises that to 20, with the host paying. Larger families can run two Tables. The details are on the Tables page.
- The host creates a Table with the family name and next year's date as the reveal.
- Pick a pack. The year ahead and The world suit mixed ages better than About each other.
- Pass the phone. Each person types a name, answers one question per screen, adds a guess if they like and holds the seal.
- Younger children can say their answers aloud while an adult types them.
- Check the lobby to see who has sealed, close sealing and export a vault file.
How do we include relatives who are far away?
The host sends an invite link. The relative writes their answers in their own Sealday and sends a return link through any messenger, and the host taps it to add the entry. The entry travels sealed, not as plain text. Relatives need the Sealday app to write theirs.
Another option is a capsule for each relative. A capsule for someone opens on their date and cannot be opened by the sender. A grandparent's birthday works well, with a short letter of up to 1,500 characters and a few guesses. Photos and voice need a sealed file and Plus.
What should grandparents record?
Ask for stories rather than facts. Where did you grow up, what was the first job, how did you meet, what dish do you make by heart, what did the street look like. A voice note of 30 seconds on the free plan or up to five minutes with Plus keeps the voice and the accent, which a written note loses.
Record in a quiet room and ask the same question to each person, so the answers can be compared. Keep the recordings short and label them with the date. Back everything up as described in backup and restore.
Which traditions work well with a capsule?
Keep the effort low. A tradition that takes ten minutes survives. One that takes an afternoon gets dropped by the third year.
- A yearly Table at the holiday dinner, with the same five questions and new guesses.
- A recipe corner: each year a family member seals a recipe and the story behind it.
- A birthday capsule from the family to the birthday person, opening next year.
- A height-and-growth photo of the kids against the same door.
- A "seal one back" reply from a relative who got a capsule link.
What should I avoid?
Avoid questions that put anyone on the spot, such as who earns the most or who will be sick. Avoid anything that could become an argument across the table. Sealday's own starters stay away from health, money outcomes and relationships ending, and a family list should do the same. If a question makes a relative hesitate, drop it.
What happens at the reveal?
Pick a calm hour after dinner. The host holds the seal, answers appear one question at a time, and the family marks each as Called it, Kind of or Missed. Kind of counts half. AirPlay to a TV is enough for a big screen. Expect arguments over Kind of, and enjoy them.
At the end, a single button starts next year's Table with the same names and moves the date forward, so the capsule becomes a tradition. The leaderboard is for bragging rights only, and no stakes are attached.
Frequently asked questions
What do you put in a family time capsule?
Predictions from each member, a recipe or story from a grandparent, drawings from children and a photo of the table.
How can children take part?
They can say a guess aloud for an adult to type, or draw a picture that is photographed and added to a capsule.
When should a family time capsule be opened?
At the next holiday dinner or reunion, one year later, when everyone is gathered.
How many people can use one Sealday Table?
Four on the free plan and up to 20 with Sealday Plus. The host pays, and guests do not need Plus.
Can relatives abroad join?
Yes. They write an entry in their own Sealday and send back a sealed link that the host adds to the Table.
