A retired German post office worker has found a message in a bottle that was launched into the sea at the start of the 20th Century. The man who dropped the bottle in the sea over a century ago was marine biologist, George Parker Bidder who released over 1,020 such bottles between 1904 and 1906. Parker Bidder, who worked at the Marine Biological Association (MBA) in Plymouth, was using the bottles to test deep sea currents. These bottles were specially designed to float just above the sea bed. With the data from the ones that were found, Bidder was able to prove for the first time that the deep sea current flowed from east to west in the North Sea .The current Guinness world record holder spent 99 years and 43 days at sea, and was released in 1914 as part of a similar research experiment.
