Aliens come in all shapes and sizes in science fiction, and often these creatures in classic films are seen wearing helmets. To create an alien costume for a small human actor, rather than resorting to expensive masks or makeup, make a space helmet out of paper-mache. Then, embellish the helmet with decorations to make it look more unique and convincing.
Blow up a balloon that is slightly larger than your child's head.
Tear six sheets of newspaper into 5-inch strips.
Mix equal parts of flour and water in a bowl to form paper-mache paste. Add 2 tablespoons of salt to prevent mold growth. The exact amount required depends on the size of the balloon: begin with two cups of paste and make more if needed.
Dip the strips one by one in the paste, then smooth them onto the balloon. Cover the entire balloon with overlapping pieces.
Apply three more full layers of paper-mache strips.
Allow the paper mache to dry.
Pop the balloon by sticking a needle through it. Then draw a hole in the paper-mache balloon cover with a marker large enough for your child to fit his head through. Cut the hole out with scissors, making sure to trim away any excess so the edges are neat and clean. The helmet will rest on your child's head, ending just below the chin.
Draw a rectangular hole with your marker in the front of the helmet for your child to see through. The hole should measure 4 inches by 6 inches with rounded corners. Then cut the hole out with scissors, again trimming away excess for neat, clean edges.
Cut the bottom inch off of two disposable plastic cups. Hot-glue a black drinking straw to the center of each cup end to simulate radio antennas.
Tape these cup bottoms to the sides of the helmet over the ears, with the open sides pressed against the helmet.
Cover the cup ends in two layers of paper mache to secure them in place. Let the paper-mache dry.
Spray the helmet with two thin coats of primer, then two thin coats of silver spray paint.
Hot-glue a dark piece of plastic transparency to the inside of the helmet to form a visor. Your child will be able to see out, but others will not be able to see in.
Plastic transparency sheets are available in teacher supply stores. They can also sometimes be found in office supply stores.
Glue an American flag to the front or side of the helmet along with the name of a space mission. You can find or create these online and print them from your computer.
Cut a piece of vacuum hose; then glue one end to the back of the helmet and the other to the body suit or backpack in order to simulate a breathing apparatus.
