What can we use if we don't have a resealable plastic bag, a small container, or strong glue?
If you don't have a resealable plastic bag to protect flat items (step 5) wrap them in wax paper or aluminum foil, use a clean metal tin or sturdy shoebox as the container (step 7), and seal it with duct tape if you lack strong glue (step 10).
My keepsakes might get crushed or the container could leak—how can we prevent damage before sealing?
To prevent keepsakes from crushing when arranging them (step 7) pad gaps with crumpled tissue paper, cotton balls, or bubble wrap and place a packet of silica gel or dry rice inside to guard against moisture before sealing (step 10).
How can we adapt this time capsule activity for younger children or older kids?
For younger children let them pick a simple theme and place pre-sorted keepsakes while an adult writes the opening date and seals the container (steps 2, 3, 4, 10), and for older kids add a USB of photos, a longer letter, and more elaborate outside decoration before sharing on DIY.org (steps 5, 9, 12).
How can we make the time capsule more special or help it last longer?
Make it more special and durable by laminating a photo and adding a silica gel packet inside with your name and opening date on the internal label (steps 7 and 8), decorating the outside (step 9), and posting the finished photo and story to DIY.org (step 12).
