Step 2Mapping everything out
iImage Information

Take out one of the panels of the ball so it won't roll away from you (don't throw away the panel, you'll need it later). Take two sheets of paper and sketch out a the shape of the mouth. take your styrofoam ball and slice it in half. Take your two plates of birch baltic wood and slide them in two the holes of the ball. tape everything with masking tape and predict how everything will turn out. The top of mouth should be at the equator of the ball and it should be spread side to side.
