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.
Step 1: What You Need
Scissors or Wire Cutters
Soldering Iron (If you want)
Coffee Cup (Any Size)
Step 2: Stab Hole
Flip over the coffee cup and stab a little hole in it.
Step 3: Cut
Now take the headphones and cut the ear pieces off after the place where the wires seperate into two.
Step 4: Cut Again
Now rip open the musical card and cut at the bottom of the wires and take out the speaker.
Step 5: Strip and Twist
Now use a wire stripper and strip off then ends of the wires on both the speakers and earphones. Now twist the wires of the speakers and earphones together. If you choose you can solder these wires together.
Step 6: Tape It
Put some electrical tape around the wires.
Step 7: Stick It in the Hole
Take the end of the wire and stick it in the hole and pull it all the way through. Once it is all the way through attach it to the bottom I used glue but tape works too. Now you are done so stick it into your music playing machine and have fun.
