Intro: 5 Minute Watertight Spy Message Capsule

for the times when you need a waterproof way to send messages to your agents (no one likes soggy spy notes)

Step 1: Materials

the materials for this instructable are proud and few
- two coke two liter bottle caps (I enter them on my coke rewards then put them in a box to use later)
- clear tape
- coded spy message, I use post-it notes

Step 2: Putting Your Capsule Together

assembly is really easy, just look at the pictures
my image notes aren't working so here are the notes
picture 1- take out the caps and note
picture 2- fold the note so it fits in one of the caps
picture 3- place one cap on top of the other
picture 4- run a piece of tape around the edge for a seal

Step 3: Enjoy Your Message Capsule

These capsules could be used as message carriers, or they could be an emergency cash stash, a tiny first aid kit, a water-tight container for when you are at the beach, or even an odd way of giving your buddy the quarter you owe him.

    It wasn't, electrical tape works a hundred times better.

    idea: What if you cut the neck from the coke bottle, epoxy a cap to the non threaded part of the neck and you got a reusable spy canister! maybe paint it camo, add a few infrared LED lights here and there, you can hide it and you can find it using a camera!

    Hot glue seals the deal much better, but this'll be fine. This gives me ideas on how to communicate to other people when I'm not there. It's like following a map to where I am... map... MAP! GREAT IDEA!!! This'll ensure proper delivery (but I guess I can step it up a notch by using a small rubber band as an improvised O-ring. genius man, genius!!!

    I like the idea - I'll be trying this out in an orienteering course for the scouts.
