Final project idea

For my final project idea, I want to make something like the paper airplane thing I saw in class. Instead of a paper airplane, t will be with a message bottle things people throw into the sea. Not only can you throw out the bottle but also receive it and you can end up chatting with the person on a message form. Though if you don’t want to talk to this person anymore you can exit and the message will be delete off. It’s like a app kind of thing, maybe they can walk around and suddenly they can pick up a bottle and start chatting with a stranger.
