With the popularity of our 1.8 ml Nalgene containers for micro caches we thought it was about time we created a How-to to help people who purchase them turn them into a top-notch micro cache. This isn't extremely complex but hopefully it will give you some ideas for your own variations. If you come up with something creative and would like to submit it to us to be published on this site, send us a note through the Contact Us form.

In this how-to, we will create a camouflaged, magnetized micro that will be attached to a metal object in some brush. We won't provide any more information because we're actually going to hide this micro and don't want locals to find it too easily!

Supplies

  • 1.8 ml Nalgene Vial
  • 3/8" Rare Earth Disc Magnet
  • Camouflage Duct Tape
  • RV Goop
  • Standard Pencil

Steps

  • Fill the depression in the lid of the vial nearly to the top with RV Goop (leave about 1/16" for the magnet so it will sit flush with the top of the lid - see Picture #2, below).
  • Allow Goop to dry about 3-5 minutes to firm up before you place the magnet in the lid. This will keep the magnet from sinking into the Goop.
  • Cut or tear a strip of duct tape 2" in length (it will be exactly the right height to make the two pieces to cover the vial - see Picture #3, below).
  • Cut the tape lengthwise (the length of the tape if it was a longer strip) into two strips. One strip should be exactly 1 1/4" tall (this will go on the body of the vial). The remaining strip should be just the right size for the lid of the vial. (See Picture #4)
  • Place the body of the vial on the 1 1/4" tall strip.
  • Be sure the body of the vial is perpendicular to the top and bottom edges of the tape - this will ensure a smooth wrap.
  • Ensure the tape is just slightly below the small lip just under the threads of the vial body. This will allow you to screw on the lid of the vial without interfering with the tape.
  • Wrap the tape carefully around the vial making minor adjustments to the tape's alignment if necessary. Your finished product should look like Picture #5, below.
  • Allow the Goop to cure for at least an hour before you wrap the tape around the vial's lid. This will keep you from knocking the magnet out of the lid and having to start over on that step of the process. The Goop instructions recommend that the Goop be allowed to cure for at least 24 hours. I recommend that you let it cure for at least that long before you attempt to test the magnetic capabilities of your micro. Otherwise, the strength of the magnet will pull the Goop right out of the lid.
  • Print the log/Geocaching info form one page at a time; re-insert the first printed page in your printer to print the second page on the back side of the first - it will make three logs/info forms (depending on how familiar you are with printing double-sided pages on your printer, this may be the most difficult part of the process). Very Happy
  • Cut each log/info form right along the edges of the text - the form should be no more than 1 1/2" wide. I like to use a paper cutter but scissors will work. Your log/info form should look like Picture #6, below.
  • Cut 1 1/2" off of the writing end of the pencil (it's easier to sharpen the pencil while it is still a normal length)
  • Tightly wrap the log/info form around the pencil stub and slide it into the vial.
  • Screw the cap onto the vial and you're ready to hide your micro!
  • You may want to mention in your listing that cachers should bring a small screwdriver, nail clippers or some other device to remove the pencil and log from the vial - it's a tight fit!
