It'll be the first place thieves check now that the internet has got ahold of it, but yesterday, this super simple PVC pipe was the perfect place to stash a spare house key. The pipe has been cut length-wise on its axis to make it look like it's buried deep in the soil when in fact, it's really just "resting" on the top.
Flip it over and there's your key.
