A time capsule is a collection of items — letters, photos, objects, recordings — preserved for someone in the future to open. Unlike a memoir or photo album, a time capsule is specifically intended for a future moment: your grandchild turning 18, your great-grandchildren, a family reunion decades from now.
The experience of opening a time capsule is unlike anything else — a bridge across time, reaching through from the past to the present. Creating one is a profound act of love and imagination.
Types of Time Capsules
Physical Time Capsule
A physical container holding tangible items — letters, photos, newspaper clippings, small objects, recipes, fabric samples, coins. Stored securely until the designated opening date.
Digital Time Capsule
A collection of digital files — video messages, photos, audio recordings, documents — stored in a format and location that will remain accessible in the future. This is where apps like Better Legacy excel: a secure, designed-for-legacy platform ensures the files are preserved and accessible.
Hybrid
A physical container with a QR code or USB drive linking to digital content — combining the tangibility of physical keepsakes with the richness of video and audio.
What to Include
Letters and Messages
The most meaningful content. Write directly to the person who will open it. Share what life is like now, what you love about them, advice you want to give, hopes you have for their future. See our guide to what to say in personal messages.
Current Life Artifacts
- A letter describing everyday life — your home, your neighborhood, your typical day
- Current newspaper or magazine pages
- A list of current prices (milk, gas, a movie ticket)
- Photos of your home, your family, your surroundings
- A playlist of songs that represent this period of your life
Family History Items
- Copies of important family photos with names and dates written on the back
- A brief family history — who your grandparents were, where the family came from
- A family recipe with a story about it
Small Meaningful Objects
Objects carry memory: a ticket stub, a coin from your birth year, a small toy, pressed flowers, a piece of jewelry. Choose items with stories attached.
What Lasts (and What Doesn't)
Lasting materials:
- Acid-free paper for written letters and printed photos
- Archival-quality photo prints (not inkjet-printed)
- Metal objects (stainless steel, copper, silver)
- PVC-free plastic
- Glass (if well-cushioned)
Materials to avoid:
- Regular newsprint (yellows and deteriorates rapidly)
- Ordinary rubber bands and paper clips (corrode and damage paper)
- Magnetic or optical storage media (floppy disks, DVDs) — these become unreadable in 10–20 years
- USB drives or flash memory — not reliable for decades
Where and How to Store
- Temperature and humidity: Store in a cool, dry location away from sunlight
- Container: A sealed metal or hard plastic container, or a proper archival box
- Location: With a trusted family member, an attorney, or in a clearly labeled secure location
- Instructions: Include a note inside about when to open it and who it's for — and tell a trusted person where it is and when it should be opened
