Want a heads up next time that annoyingly chirpy coworker is heading over for some annoyingly chirpy chitchat? Rig up this little system and you'll never be caught off-guard again.

To complete this How-To you will need:

A clothespin
Some aluminum tape
Some red electrical wire
Some black electrical wire
A wire cutter and stripper
A battery-powered noisemaker
A 9V battery
A 9V battery holder
Some fishing line
A sheet of paper

Step 1: Wrap aluminum tape around clothespin tips

Wrap aluminum tape around both tips of the clothespin, leaving a tab on each end so you can attach wires.

Step 2: Tape electrical wire to clothespin

Cut a piece of black electrical wire, strip both ends, and tape one end to one tip of the clothespin.

Step 3: Connect negative pole to other tip

Locate the wire running from the negative pole of the noisemaker—the pole marked with a minus sign—and connect it to the other tip of the clothespin.

Tip: If your noisemaker doesn't come with wires already attached, just cut and strip another piece of your own to use.

Step 4: Connect wires to battery holder

Locate the wire leading from the positive pole of the noisemaker and connect it to the battery holder. Now do the same with the remaining black wire coming from the clothespin.

Tip: You've just built a completed circuit. Connect the battery to make sure it works. Now DISCONNECT IT!

Step 5: Fold paper & string fishing line

Start folding your sheet of paper into a triangle, but stop halfway. Now string the fishing line across the strongest crease, tie it off, and finish the triangle.

Step 6: Put folded paper inside clothespin

Put the folded paper inside the clothespin.

Step 7: Tape to inconspicuous place

Tape the clothespin, noisemaker, and battery to an inconspicuous place in your coworker's path.

Step 8: Run fishing line to secure anchor

Run the fishing line to a secure anchor across the way.

Step 9: Wait for "Mr. Chirpy" to head your way

Now just wait for "Mr. Chirpy" to head your way.
