Do you like geocacheing? If so, then I've got the instructible for you. Here's an easy way to build your own supper simple and and fun geocache to use. Any small container will work for this it just has to have a cap and be water resistant, unless your going to put it in the bottom of a lake in which case it will need to be water proof, there's an interesting idea scuba geocacheing. I hope you enjoy my instructible.
