Wish I could say I did dive. Actually, my mom found this bottle while diving, in the early 60's. She actually held the worlds record for catching the largest octopus, free hand. Only lasted for about six months but she was proud of it.
Anywhoo, the bottle is one of many. It just happens to be my favorite so I thought I'd research it a little.
I think their great. I used mine to propose to my wife. I enclosed a pirates treasure map that led to her ring. Strategicaly buried it on the beach in Hawaii and played it off like the discovery and the quest was all by chance[].
I laid mine in my jade plant to keep it on display. Then I added others in them to keep the cats from digging in them for sport. Buggers. The bottle was put in about 2 years ago, and the plant has grown to basicly entomb it - I can't get it out now unless I move the plant more than it really wants to move....
