Step 1: Materials

Picture of 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 doesn't really seem like the tape is very waterproof.....

Exactly, but the title of this instructable says just that: '5 minute watertight spy message capsule'.
It's watertight for 5 minutes... ;)

Very good point sir!

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!

I like the idea, I used a similar setup on one of my mini spud guns. Good idea!

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.
