'EvD' This is a classic "message in a bottle". Although, you must write the message with your iPhone. Write a message and throw it to the sea...some day, some lucky one will find your bottle and get your message from the past. When you've wrote the message, place the iPhone on the cover (lower part of the bottle). Then screw the upper part tightly to lower and your bottle is ready to sail!
