Materials:

1. A BOX, either a cardboard one or preferably, a styrofoam box. If you use a cardboard box, a shoebox will do, but a small corrugated cardboard box (one with those little tiny spaces between the sheets of cardboard) will work better.

2. RUBBER BANDS. You should try a variety of rubber bands to see which make the best sound. In general, the thicker the better (since there is more stuff vibrating it should be louder), but if you TOO thick a rubber band, it might collapse the box, especially with a shoebox.

3. A cardboard TUBE.


Procedure:
1. First, just stretch a rubber band, pull it and then let it go. It should vibrate quite visibly. Notice, however, how quiet it is. That is because the only thing vibrating is that little piece of rubber.

2.Cut a hole in one of the sides of the box and insert the cardboard tube.
3. Take the rubber band and stretch it around the box so that it passes over the open top of the box.
4. Pluck the rubber band and you should hear the sound as much louder, especially with a corrugated cardboard or styrofoam box. You should be able to feel the box vibrating when the string vibrates. 5. Put more rubber bands on the box. Be careful, if you wrap TOO many rubber bands around it might collapse and/or break the box.

6. To tune your rubber band box guitar, you can make the strings tighter or looser across the open top. Take the rubber band at the side of the box and stretch it out and down to make it tighter. When you put it back against the box, the rubber will have enough "grab" to hold on the the tuning for a while. Experiment with the other rubber bands to find a tuning you like.
