Hey, you got something to hide?!
A few years ago I made this shaving can safe, and outlined how I made it in this Instructable: Shaving Can Safe (that Still Shoots Foam!).
Then I recently made a slightly easier version that uses a spray paint can, seen here: Spray Paint Secret Safe.
I thought it would be fun to put together a collection of some of my favorite hiding places made by other Instructables members.
And here they are: unusual, clever, in-plain-sight hiding places (also called "diversion safes") that you can make.
Step 1: Outside Overhead
Step 2: Inside Overhead
Step 3: In the Yard
Step 4: In a Log
Step 5: Anywhere Indoors
This is an almost classic idea nowadays, and there have been many tutorials shared on how to make a secret outlet cover safe.
The one-and-only King of Random made one of the early versions, excellently documented here: How to Make a Super Secret Safe - for Less Than $3
Step 6: In a Book
Speaking of classic hiding places, I don't think there's a more well-known idea than using an old book!
This is an idea that's been documented many times, by many authors. It may be an older idea, but there's a reason it's so popular: it's a GREAT idea!
Step 7: Tiny Objects
Author assemblyrequired made a couple of my favorite hiding place ideas:
