Converting a coffee bottle to a geocache


I have been, or can be if you click on a link and make a purchase, compensated via a cash payment, gift, or something else of value for writing this post. Regardless, I only recommend products or services I or my family use personally and believe will be good for my readers.

As a geocacher and a CO (cache owner) I find it important to keep our playground as nice and clean as possible. As the playground is the planet we live on … the Earth … and I know that reusing is even better than recycling I knew it immediately when I bought my first bottled coffee that I also found really taste that its bottle’s shape and size is just perfect to become a geocache.

There are many different shapes and sizes you can find coffee at stores and filling stations. If you want to use them as geocaches look for the big mouth, that is important for easy use.

The materials

First step is to clean the bottle. On the above picture you see a different color cap on the bottle. I prefer using those caps coming from the same brand but different drink. The reason for that preference is that as the geocache will be out in the wild exposed to all the elements over time its camouflage will slowly get worse or with some geocachers not to cautious it might even be gone from the cap and with that color it will still be less visible to the muggles.

You will need some camouflaging tape as well and a general purpose glue. Those tapes are available in all different colors for different hiding places. Originally they are used by hunters, photographers and anyone who loves to go out to the nature and observe it without easily being spotted. They are designed to cover guns, spyglasses, objectives, etc. Their texture is serving as a glue, if you pull it and stick it over itself it’ll stick. The reason why I still glue it together and to the bottle to make it last longer and keep its position better. Let me mention here that the same material is available in different stores to hold bandage in place and sometimes it is available in camouflage colors when I see it I always buy some as that is a lot wider then the ones I found online so far.

Camouflaged coffee bottles

As you see above the outcome is really cool. Earlier I tried to use different duct tapes for similar purpose but that had some issues:

  • Tape did not follow properly the shape of the bottle. I tried to cut into it here and there to follow better but not much luck with it.
  • Over time, especially in warmer areas the tape started to leave the bottle alone and got loose
  • The cap was not too easy to cover (in a later post I’ll show how I converted these same bottles to a magnetic hide for guard rails and you’ll see it there)
  • The duct tapes are mostly shiny and such it is almost shouting to the muggles: “Look here I am!”
The geocache with its content

When it all dried up nicely I fill it up with a logbook, a pen and some swags that fits. I usually let it dry for a few days just to make sure it is all stuck together properly. I prefer preparing the logbook myself, not because of the costs but because it gives it a small nice extra touch when someone finds it. If I prepare a geocache to replace a previous one I prepare the logbook even further to have the GC code on the front page with the name of the geocache as well. Inside that tiny logbook I have all the information card printed across a few pages. I add a plastic bag for extra protection. Mostly these bottles stand good against water and last a few years without a problem.

As you can see I don’t use a full pen in the geocaches but only the inner part, now that is for costs purposes. Sometimes as I stay at hotels often I get some of their pens and place them into geocaches.
