Picture of Hide-A-Key in a Sprinkler!

One of the most annoying things in my world is walking home from school to find that nobody is home and the doors are all locked.  I have a bad tendency to forget my house keys everywhere, mostly on my desk in my house where they're not helping anyone.  Long story short, I saw a sprinkler-shaped hide-a-key in a catalog and it hit me that it was a genius idea!  Oddly enough, it cost close to $8, while a "real" sprinkler with all the mechanics inside often costs far less than that.  I found an unused sprinkler in the shed and got to work... I present to you: the Sprinkler Hide-A-Key!

Waterproof, inexpensive, inconspicuous, and quick to build - let's go!

Step 1: Stuff You'll Need

Okay, brace yourselves, here's the parts list:

-A sprinkler*
-A dime.  Yes.  A dime.

you'll also need a hot glue gun, but that's it!

*This might seem obvious, but it's generally good practice to find a sprinkler that your keys will fit inside of.  If possible, open up the sprinkler you plan to purchase/use to see if your keys will fit.  If you have a car with a large key fob, you might have a harder time finding the appropriate sprinkler.

Very good idea about the fins. I would never have thought of that.

That's pretty clever.
