What Geocachers need to find is called a Geocache. And creating a Cache to hide can be almost as addictive as the sport itself.
To learn more about Caching check out geocaching.com and opencaching.com .
Another great resource dispensing indispensable news and geocaching trivia is a top notch Pod Cast at www.podcacher.com
I've designed this container be long enough to hold a pen, and generous sized cache log.
After searching around the Instructables.com site, I found several very good instructables of two bottle tops being bonded to create a much smaller container which would be know in the Caching world as a micro cache.
Here's a few versions that may suit your needs if this instructable isn't quite your flavor:

Step 1: LIST OF INGREDIENTS
- 3/4 INCH PVC TUBE
- HACK SAW
- PLASTIC POP OR WATER BOTTLES WITH SCREW ON CAPS x2
- DREMEL OR OTHER ROTARY TYPE TOOL WITH SANDING DRUM ATTACHMENT
- OSCULATING SANDER WITH SANDPAPER
- PVC CEMENT
- STANDARD PAPER SHEET x2
- SPRAY PAINT (VARIOUS CAMO) Shown in Intro Image
Step 2: CHOOSING THE LENGTH
Then mark a cut line directly on the tube..
Step 3: MAKING THE CUT
(I just braced it against my knee).
Step 4: TIME TO HIT THE BOTTLE
I found that lightly scoring the area to be cut, wile slowly rotating the bottle, made for a nice straight cut all around.
The second image shows the bottle top separated from the bottle.
OPTIONAL: IF YOU BOTTLE HAS A RIDGE DESIGNED FOR CARRYING,YOU MAY CHOOSE TO CUT ON EITHER SIDE OF THAT. I DECIDED TO INCLUDE THE RIDGE IN CASE I WANTED TO USE FOR SECURING A STRING TO LATER IF I DECIDE TO HANG THIS CACHE FROM A TREE.
Step 5: SMOOTHING THINGS OVER (PVC)
Try fitting the bottle top over the end of the PVC tube as shown in the first photo of this step.
If they will not fit snugly together use a sander (or hand sand) to smooth the outer rim of the PVC tube.
I found that a Dremel with sanding drum attachment worked well on the inner rim of the PVC.
Step 6: OUT OF THE ROUGH (Bottle Tops)
Try fitting the PVC and Bottle tops together again.
Notice the tapered outer rim of the PVC in the second photo of this step. I used the sander in an attempt to assist the PVC into a snug fit, but found using the Dremel again in the NEXT STEP proved to be a better solution.
Step 7: MAKE IT FIT
Rotating the PVC tube incrementally while attempting as best as possible to remove equal amounts of material all around, apply the Dremel sander attachment lightly, and check your fit with the cut bottle top often until a snug fit is obtained.
Do this for both ends of the PVC until you are satisfied with the results.
Step 8: STICKY FINGERS
If your choice of cement came with a dabber affixed to the inside of the lid, apply lightly to both the outer rim of the PVC tube area you've sanded, as well as to the inner neck of the cut bottle top.
Depending on your cement, and amount applied, it may dry quickly, so just work on one bottle top / PVC combination at a time.
Once both parts have cement applied, fit them together and apply some pressure while rotating approximately a quarter of a turn.
This will help both parts to bond better.
Once satisfied, repeat the process on the other bottle top / PVC set.
NOTE: As a precaution, leave the screw on caps off their perspective bottle tops until the cement has dried and cured to avoid accidentally permanently affixing them to the bottle tops. Cement should cure completely after several hours.
Step 9: OPTIONAL ADDITIONAL STEPS (Log Sheet Pt 1)
However, if you would like to continue with completing a ready to hide geocache container to impress your fellow Cachers, you'll need to include a Cache Log.
Take a couple pieces of paper and set your Cache container near one edge.
From here you will decide which length is best to fold in half to create a Log Sheet suitable for your container.
After making the fold, use a pair of scissors to cut along the fold.
Stack your resulting sheets of cut paper, then place a couple staples at one end, effectively creating a small booklet.
Step 10: OPTIONAL ADDITIONAL STEPS (Log Sheet Pt 2)
Alternately, you could create a more refined Cache log on a computer and print before the cutting stage, download and print a log sheet online at Geocaching.com, or use lines paper and just add information you want displayed on your Log Sheet.
Once the log has been created, you might like to wrap it around the pen and insert the rolled package inside your new container, replacing the screw on bottle caps as shown in the last photo of this step.
Step 11: CAMOFLAGUING YOUR CACHE
I hung my container from a thread while making short brisk passes with various spray paints to obtain a nicely camouflage look.
Maybe covering your container with glue and rolling it in fallen pine needles, dirt or sand might be another option (not shown here)
Be creative, and most of all, have fun.
