This is an instructables about a very small, discreet, watertight survival tool that can be made for a couple cents. I have used them and they are almost flawless! Hopefully they will help in all of your camping endeavours.

Step 1: Supplies

1. Plastic disposable straw
2. filler of your choice (cotton wad, triple antibiotics, food seasonings, etc.)
3. Long thin object (screwdrivers, pencil, etc)
4. pliers
5. match or lighter
6. scissors

Step 2: Step One

First, take the straw and cut it in to about 2 in. lengths (this can be varied depending on how much stuff you want to put in).

Step 3: Step Two

Second, crimp the straw on one side with the pliers leaving about an eighth of an inch of hang over. Then take the match or lighter and slightly melt the straw. Remove the heat and hold tight with the pliers for 30 seconds to a minute.

Step 4: Step Three

In my example I use a cotton wad for a fire starter. Take the wad and pull a small piece off. Then, use your long skinny object to shove it down into the tube. Repeat until full with about a 1/4 inch left over.

Step 5: Step Four

Use the pliers and matches to crimp and seal the other side. Voila! it's done! Get creative with your filler ideas and let me know about them! Happy camping.
