Make a Secret Hidden Safe with a Wall Outlet

DIY web site Instructables details how to make a secret—albeit very small—hiding place for your valuables by installing a fake wall outlet. The execution could use some tweaking (surely the faceplate should be a bit more secure, like this fake outlet designed for the task), but in all it’s a fun idea for hiding your mini valuables. If you’re a fan of the secret hollow book, this might be worth a try.
