In this instructable you will learn how how to a make great speaker out of a coffee cup. This speaker will connect through a headphone jack and is very good for playing songs for friends loudly. This will produce more sound than just putting a headphone in a cup and will only cost you about a dollar more. Credit to fungus amungus and some others that have made stuff like this for the idea. I hope you find this helpful and please vote for me in the coffee cup contest.
