Have you ever thought about sending a message in a bottle? When I was a kid I found a balloon with a message inside and thought that was pretty cool. The note inside the balloon gave me the name and address of the person who sent it so I wrote them a letter back. I don't remember where it was from, but I remember how cool I thought it was.
I bet it was pretty cool for this 14 year old kid to find a message in the bottle he found in the river. Even cooler when he found out it was 35 years old! http://www.wcax.com/story/19060309/message-in-a-bottle-surfaces-35-years-later
