This sprinkler head may look like a typical lawn-watering device, but it really isn't: It's actually a key holder that will help you hide your house keys in plain view of all potential trespassers.
The $5.99 plastic, water-tight sprinkler head comes with a screw-on top, and although it looks quite realistic, it won't keep your begonias alive. Even so, it seems a lot safer than hiding it in a potted plant or even more obviously, under your doormat. Or you can do what I did in college—tuck your key behind a black widow's web and hope anyone looking to get in is afraid of spiders. [Product Page via BBG]
