For the U.F.O. you will need: Styrofoam or paper bowls (paper is better), paint, brush, scissors, glue and decorations.
Cut an opening in the bowl.
Paint bowls. I would do this first, even though the pictures do not show this.
Allow paint to dry.
Glue bowls together.
To make aliens you will need: Pom - poms (2 sizes), pipe cleaners, foam sheet or felt or construction paper for the feet, glue, scissors. and wiggly eyes.
Cut out feet and glue on to the bottom of the bigger pom-pom. Cut pipe cleaners. Glue on and decorate.
