Here are some pictures on how to make my homemade iPod speakers. What you need: 2 pieces of paper, tape, k'nex (can be replaced), and headphones. You can just look at the pictures to make it, its pretty easy. You can replace the base of you don't have any k'nex. Just make a cone out of the paper and insert the ear bud and tape it, do the same with the other ear bud. Then make the knex base, or your own and add the speakers. There you go, instant iPod speakers. Here is a video to show you how the sound is.
