Rather than letting the rocks and shells you so carefully collect on vacation get lost in a drawer among paper clips and thumbtacks, put the found objects in jars. A small vessel requires only a few items to fill it. Once you label the jars with the place and date and line them up on a shelf, you'll have a time capsule display of trips past.
