This instructable will teach you how to make a small container from two bottle caps and a bottle neck. It's a great way to re-use bottles that you may have been throwing out.
I just wanted to acknowledge that this is not a completely original design. I got the idea from the Groundspeak forums, especially the user "Odie442". However, there is no existing instructable, and I'm sure that everyone will appreciate it. The pictures and text are all original though.
The container can be used as a micro geocache. If you don't know what geocaching is, check out www.geocaching.com or one of the many instructables here that can teach you what it's all about.
Besides that, these could be maracas, fishing bobbers, boxes to hold small beads, game pieces... anything you can think of! Just don't bother doing steps 4-9 if you don't want it to be a geocache.
Step 1: Materials
To make the basic container, you will need:
1. A plastic soda bottle with cap
2. Another soda bottle cap (short, mine is from a coke)
To make it into a geocache, you will need on top of that:
4. A dark permanent marker
5. A pencil
6. A hot glue gun, with glue stick
7. A fine toothed saw
8. A sheet of paper
Also, other bottles, adhesives, cutting materials, etc. can be used. People have a lot of success with 1/2 L water bottles as well as gatorade bottles. Tyvek can be used in place of paper for a waterproof log scroll. However, this is all I had at the time.
