Be the hero of the party and make your own DIY Electric Party Cup Speaker! All you need is a pair of earbud headphones that you're willing to cut with scissors, some small alligator clips, a length of thin copper wire, a magnet, one of those red party cups (we're sure you've got some of those around the house after that wicked kegger you threw last weekend) and some tape to hold it together. This is more than just sticking your phone into a cardboard tube. This little do-it-yourself project is costs next to nothing, and can be rigged up in a few short minutes. The sound isn't too bad considering what you'd have to pay for a manufactured speaker of the same size. Give it a try!
