Everyone knows about hiding a key under a rock. Thats no longer a secret. But randomly burying a key could mean you lose it forever! By using a small rock no one will think a key could be under it, But, by pulling it up you reveal a jar hiding anything you need.

Step 1: Materials

For this you will need the following:
Glue (any kind should work. I used hot glue).
A rock of your choice, the rougher the better.
A jar capable of holding what you need.

Step 2: Creating

Give the rock and jar lid a good cleaning. You can skip this step, but the glue will have a hard time holding onto the rock/lid. Roughing up the lid with sandpaper will help as well (but rinse the shavings off after!)
Sprinkling dirt over the glue will help hide the jar and cover the glue.
