This project could also be titled "How to spend two weeks covered in plaster and clay, being completely frustrated, and having your family and friends think you are nuts." But...the aliens came out fantastic and as we count down the days until Halloween, I become more and more excited to show them off in our Area 51 display.

Materials used:
* 18" plastic skeletons
*  Foam alien heads (purchased online)
*  Expanding foam
*  Plaster of Paris
*  Plaster material (sold in a roll at Michael's)
*  Modeling clay
*  Spray Paint

Step 1: Alien Anatomy Lesson

Picture of Alien Anatomy Lesson
Purchase 18” plastic skeletons. Remove head. Remove arms and legs. Remove hands from the arms and feet from the legs. Reattach the hands to the leg bones and the feet to the arm bones. Reattach the legs where the arms were and the arms where the legs were.

Step 2: Expanding the body

Please be sure to wear gloves when using the expandable foam. Protect any surfaces with cardboard or plastic. It does not wash off your body or other surfaces easily!

Fill chest cavity with expanding foam. Unless you want little fat aliens, do not use too much expanding foam in the “belly area.” It will continue to expand for several hours. In this case, less is better! Build up neck, arms, and legs with expanding foam.

Step 3: Creating the body

Cover entire body with plaster material, cut into strips and dipped in water (available at Michael’s). Allow one side to dry completely before completing other side. Dry overnight.

Step 4: Smooth it out!

Mix Plaster of Paris with a small bit of water to create a paste (so that the Plaster does not crumble). This step is to create a smooth skin surface on the alien. Using a foam paint or craft brush, cover the entire surface of the alien. I would recommend doing the backside first. Allow one side to dry completely (overnight) before attempting the other side.
