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 did that, it works good!

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.
