We started with 2" thick foam board glued together to form a block that would be carved down to form the head...

The basic shape to be carved was drawn
on with marker. This helped keep the sides uniform. A dremel tool was used to
do most for the shaping...
This is the basic shape of the head before the hoses, teeth and other misc. items are installed...

Well as you can see we skipped alot of pics during the building process. It's body is constructed from pvc pipe and fittings covered with layers of spray foam and different size corrugated hoses...

Full view in it's upright position ...

This is the lifting system behind it's body. The five gallon bucket sitting there for added weight to the base. We used two concrete blocks for the big night. It takes two stormdoor closer to lift the alien at 105psi. We got the idea for the lift from Cliff Martin at 2 ScaryGuys.com. His site is in the links section back on the main page...

We used coat hanger wire for the frame work in the hands. Then applied layers of foam and formed it around each finger before it was totally dry...

Here are the teeth in clay which we made silicone molds from and cast the final set with Por-a-cast from Monster
Makers. Also in the links section...

Good side view. The head was coated with a thick layer of epoxy for protection and strength. Then the entire body was sprayed with gray latex primer before the final airbrushing...

After airbrushing...

These are egg pods. Which we used as part of the fog effect.

Airbrushed semi open pod...

We poured epoxy resin into the cavities and down the sides for an oozing effect.

Open pod.

Air powered face hugger. The three hoses in the snout whip around. Really makes guests jump when looking at him upclose!!!

We added three more egg pods.... this shows the original three.

This is the inner jaw/teeth extended out from the outer teeth. We used another stormdoor closer and pvc pipe to created the movement. We added a few strips of flat silicone to the sides of the outer jaw.

With the added lighting effects, fog, plus two soundtracks we had quite a few kids screaming and made several adults jumpy! THE BIG PAYOFF!!!!!!

This is how we constructed the light beacon towers. Two 5 gallon buckets, one cut in half and screwed to the bottom of the other. Painted black with latex house paint.

Its hard to get good pics in the lighting used through out the project. This gives you the basic idea.

If you think this is cool check out H.R. Giger's works. He is the designer/artist behind the Alien Movies. Well worth looking into!!!
