Make a water resistant ,hard match case that floats out of an old flashlight.
Step 1: Disassemble
I had several small flashlights that I couldn't fix so I found another use for them.
Remove the battery case and pitch it. Your don't have to remove both ends just one will do.
Step 2: Matches
I used waterproof matches. Don't forget to include the striker. Then close it up and you have a water resistant match case.
My guess is that it probably is waterproof but I'm not sure what the definition of waterproof is so I'll just stick with water resistant.
