Consider this modern update on the age-old "Message In a Bottle" we'd all might have tried in our younger days. Then, we ineffectually used rolled-up handwritten notes in a well-sealed glass bottle, tossed in the ocean during high tide.
I'm unsure how well the included USB memory stick might hold up to the corrosive effects of salt water, and skeptical that anyone who might find it would have a computer, and trust it to be not infected with viruses!
