Time Capsule Hole
On a Flat Sandy Beach
Bury a message, a memory, or a wish — and dig it up another day — adapted for flat sandy beach conditions.
About This Hole
The gentlest project on this list, and the one with the least to do with engineering: children write or draw a message — a wish, a memory of the day, a note to their future self — seal it in a waterproof container, and bury it somewhere memorable on the beach. Unlike every other hole here, the point isn't the digging itself but what happens afterward: marking the spot, remembering it, and coming back to dig it up on a future visit.
About This Beach
Gently sloping beaches with fine to medium sand — the gold standard for hole digging. The sand is usually damp enough to hold shape a foot or two down, making these beaches ideal for almost every hole type. Common on Atlantic and Gulf coastlines.

How to Dig It — Flat Sandy Beach Edition
- Have each child write or draw something on a small piece of paper — a wish, a favourite memory from the day, or a message to themselves for next time.
- Seal the paper inside a small waterproof container, such as a screw-top jar or a resealable freezer bag wrapped in another bag.
- Choose a spot well above the tide line, ideally near a landmark that won't change, such as a groyne, breakwater, or fixed dune marker.
- Dig a hole around 20–30cm deep, place the container inside, and cover it completely.
- Mark the exact spot with a photo, a note on your phone, or a description in relation to the landmark, since sand shifts and the exact position can be surprisingly hard to recall.
- Agree on a return date — the next holiday, next summer, or even just 'the next time we're here' — and dig it up together to reread the message.
Variations: For a family group, bury one shared container with a message from everyone rather than individual ones. For a longer-term version, note the GPS coordinates on your phone if you're not confident the landmark will still be there next time.
