Create a Mother's Day Time Capsule
A Mother's Day time capsule is a sealed collection of letters, voice recordings, photos and videos made for a mother by her children, given on one Mother's Day and set to open on a later one — next year, in five years, or on a birthday of hers. One of you assembles it, and it stays locked until the date you chose.
A card has room for two lines, and both of them were printed before you bought it.
A capsule is where the rest goes: what each of you would say if nobody was reading over your shoulder, in your own voices, delivered on a day when she is not expecting anything.

What a card has no room for
Most of what people feel about their mother is specific, and almost none of it gets said. It is the lift at six in the morning, the phrase she uses when she is pretending not to worry, the thing she cooked when someone was ill. Cards do not have a line for that.
A capsule does, and it adds something a card cannot: time. Said today and read today, a thank-you is a nice moment. Said today and opened in five years, it arrives with the voices of grandchildren who have since grown a foot, and a letter from a version of you she had half forgotten.
It is also a gift that costs an evening rather than money. A capsule that opens within a year is free, which makes next Mother's Day a reasonable place to start.
Who makes one, and for whom
The same capsule takes four quite different shapes, depending on who is doing the making.
Grown children, together
Brothers and sisters each write a letter and record a few minutes of sound or video. One of you creates the capsule and uploads everything; the others send their files to that person.
A partner, for children too young to write
Record them answering three questions about her, scan the drawings, film the breakfast they insisted on making. In a few years those voices will be unrecognisable, which is the whole value of it.
Her first Mother's Day
Written in the first year, by her or for her, and addressed to the child as well. It can open when that child is grown: a recipient can be a name saved in your contacts, with no inbox needed yet.
For a grandmother
Three generations in one capsule: her children, their children, and a recording of her telling the story everyone asks for. Record it this year rather than next.
One author, several children
A capsule has a single author. Only the person who creates it can add files and text, so brothers and sisters do not each log in and upload: one of you is in charge, and the others send letters, recordings and photos to that person by email or message.
Pick the sibling who answers messages. Give everyone the same short brief — one letter, one recording under three minutes, one photo she has never seen — and a deadline a week before the day. Nothing is recorded on our site: each of you records on your own phone, and the author uploads the files.
The trade is worth naming. Whoever assembles the capsule sees everything in it. If one of you wants to say something the others should not read, that is a second capsule, made by that person and meant for your mother alone.
Mother's Day time capsule ideas
Pick four, not forty. The ones that age best are the specific ones.
From each of you
- A letter that starts with one particular memory rather than with thank you
- The thing she taught you that you now catch yourself doing
- An apology you have been meaning to make since you were fifteen
- What you understood about her only once you were an adult
- A question you want her answer to on the day it opens
Sound and video
- Each grandchild saying what Grandma is like, unprompted and unedited
- The family singing the song she always sang, badly
- A voice note from each of you, recorded alone, two minutes at most
- A video of an ordinary Sunday at her table
- Her own voice, telling the story you always ask for
Things to scan or photograph
- Drawings and cards the children made this year, before they go in a drawer
- A recipe in her handwriting, and a photo of someone attempting it
- One photo of her from before she was anyone's mother
- This year's school photos, with heights written on the back
- The front of the house, the kitchen, the garden — as they are this spring
One capsule takes all of it at once: the letters in the message, and the recordings, scans and photos as files.
Start with the recordings
Letters can be written the night before. The children's voices take a quiet ten minutes, so record those first and add the rest as it comes in.
Which Mother's Day should it open on?
Next Mother's Day
A year is long enough for her to have stopped wondering what is in it. A capsule that opens within a year is free, so this is the easy first one.
In five years
The grandchildren's voices will have changed, some of the predictions will have resolved, and the letters will read as written by slightly younger people. Far enough to surprise, near enough that everyone is still reachable.
A milestone birthday of hers
Her sixtieth, her seventieth, her eightieth. It gives the day something nobody else will have thought to bring.
The year the youngest leaves home
The quietest year in a mother's calendar. A capsule full of the noisy years lands at the right moment.
Some families make it a habit: a new capsule each Mother's Day, each opening on the next. After the first year there is always one to open and one to seal.
When Mother's Day falls
It depends where she lives. In the UK it is Mothering Sunday, the fourth Sunday of Lent, which puts it in March or now and then in early April. The United States, Canada, Australia and many other countries use the second Sunday of May. France uses the last Sunday of May, or the first Sunday of June in the years when that Sunday is Pentecost.
The date moves every year, so set the opening date from a calendar for the year you have in mind rather than by adding twelve months to today. A capsule opens on the date you give it, not on the occasion.
How to give it on the day
A sealed capsule is invisible by design, so the giving needs an object.
Make yourself the recipient
Recipients are emailed when a capsule is created, as well as on the opening day. For it to be a surprise on Mother's Day, create the capsule with yourself as the recipient. The capsule is identical; only the notification differs.
Put the link in a card
Once the capsule is sealed you can share its link or its QR code with anyone. Print the QR code or write the link inside the card. Scanning it shows a locked capsule counting down to its date, and nothing else. For that to work the capsule has to stay viewable by link, which is the default; add a password with a hint if you want to restrict who can open it on the day.
Tell her the date, and to keep the card
Say when it opens and who is in it, not what anyone wrote. With yourself as the recipient, the opening-day email comes to you, and the link in the card is how she opens it — so the card is worth keeping.
Or skip the surprise
Add her as a recipient and she is emailed straight away that a capsule is waiting, without being able to see inside, and again on the opening day. Less theatre, and the email that matters reaches her directly. It is also the only case where a private capsule makes sense: private means recipients only, signed in with the address it was sent to, so a link in a card would show her nothing.
Practical notes
Whoever the recipients are, name more than one: you and a sibling if it is a surprise, her and at least one of you if it is not. A capsule with a single recipient depends on a single inbox still being in use on the day, and recipients cannot be added after sealing.
Free capsules include 300 MB of storage and paid ones 1 GB, with more available for a one-time fee. Letters and scans take almost nothing; video is what fills a capsule. Trim each clip to the part that matters.
Once sealed, nothing can be added and the date cannot be moved — not by you, not by her, not by us. So set a deadline for the slowest sibling, and seal without them if you have to. When the capsule opens, it stays open for the window you chose and is then deleted from our systems, so opening day is the day to download everything.
If your mother has died, or the day is a complicated one for you, a capsule can be addressed to yourself or to your own children instead: what you know about her, kept for the people who will ask.
