This is my first instructable so please tell me what you think and what i can do better in a next instructable :D
Step 1: Choosing the Right Container.
If you have chosen for a wooden box, make sure to regulary check of your wood is still in a good condition and is not falling apart due to moisture
Step 2: You'll Guess It, Choosing the Right Place to Put Your Safe Under the Ground
1: Not in a place where a lot of people walk because there is a risk of the container breaking under the pressure.
2: In a corner of your garden under the ground/grass where plants grow that don't need to be changed every year because your safe might get found while someone is changing the plants.
If you have to put your safe in a place where a lot of people walk you shouldn't choose a glass container, a wooden box would better fit that situation.
Step 3: Making the Hole
Step 4: Putting the Container in the Hole
Then put soil over it with grass so that it will be harder to see the just dug hole.
Step 5: Make the Place Where Your Safe Is Look Like You Haven't Buried It There
My place wasn't that clean after all but I am sure you can do this much better!
Don't forget the secret place by yourself :p
