Seal a Family Time Capsule to Open in Five Years

Ask an eight-year-old what they want to be when they grow up, write the answer down, and put it away for five years. At thirteen they open the box, read their own handwriting, and ask to read yours.

Before you start: these answers are personal, and they stay on paper. Read the safety note first.

How it goes

1. Pick the opening date together and write it on the lid in marker. Five years gives the answers time to change.
2. Your child drafts questions first, on paper, before anyone opens a chatbot: favourite food, the song stuck in their head, the thing they worry about at bedtime.
3. Ask the AI to widen the list. Type: We’re making a family time capsule to open five years from now. My child is 8. Suggest ten questions each person can answer on paper, where the answer is likely to change by then. Include two for a grandparent. Nothing about where we live or go to school.
4. Your child cuts the list to ten, crossing out anything dull and keeping at least half of their own.
5. Everyone answers by hand, one sheet each, sealed in an envelope with their name on the front. Adults answer too, and nobody reads anyone else’s.
6. Add three ordinary objects: a drawing, a receipt from a normal week’s shopping, and a photo printed at home.
7. Seal it together. Give the capsule a name, write it on the lid under the date, and put it away.

Who does what

AI suggests questions a child would not think of, such as “what does a normal Saturday look like?”

Your child writes and edits the questions, runs the answering session at the table, and chooses the objects.

You type the prompt, fill in your own envelope with care, and pick where the box lives.

Make it easier or harder

For a six-year-old: swap written answers for one drawing per question, and write a caption underneath as they dictate it. Trace their hand on the inside of the lid.

For a twelve-year-old: add a page of predictions. What will a phone look like? What will a loaf of bread cost? Who will be tallest in the family? On opening day, the predictions are the page everyone reads aloud.

Take it off the screen

The chatbot’s part ends with the question list, about ten minutes in. Everything after that happens at the kitchen table.

The US National Archives advises keeping family papers out of “damp basements, garages, and hot attics”. It also warns against rubber bands, non-stainless paper clips, and old sticky tape, all of which damage paper and photographs. A shelf at the back of a bedroom wardrobe beats a hole in the garden.

When it goes sideways

Oglethorpe University, home of the International Time Capsule Society, estimates that 80 percent of time capsules end up lost, through theft, secrecy, or poor planning. You can fix the planning part tonight. Put the opening date in your phone’s calendar with the box’s location in the note, and tell one relative where it is.

If your child wants to open it next month, give them a smaller envelope marked “open in one year” to fill instead.
