A skull can be made out of paper mache by using a day-old inflated balloon. Shape the jaw and mask around the balloon. Paper mache skulls can be used as a decoration for Halloween or as a symbol for the popular Mexican holiday Dia de los Muertos.
Step 1: Make the jaw
Setting the day-old balloon on top of an open jar, start wrapping masking tape around the balloon. Wrap the tape to about one-third of the way up from the bottom of the balloon, creating a jaw-like shape.
Step 2: Complete the mask
While wearing protective gloves, use a paintbrush to start applying diluted glue over the balloon. Cover the glue with a piece of tissue, apply more glue on top and then cover with more tissue so it slightly overlaps the first. Complete this all the way around the balloon so that there's at least two layers of tissue covering the surface. When the balloon is completely wrapped and dried, pop and remove the balloon.
Step 3: Decorate
To make the model lean backwards when placed down, cut a slanting hole near the base of the skull. Cut out holes from the paper mache for the eyes, nose and mouth, and affix tissue on the inside of the skull to cover the holes. To make the skull glow as a decoration, place it on top of a small, battery-operated light.
