Yes indeed, a message in a bottle thown in the ocean in one country can be found in another country accross the world.

Last year, a high school student named Corey Swearingen put a letter in a bottle, sealed it up, and dropped it in the Atlantic Ocean, off the Florida coast. It was kind of an experiment for school.
