Or it could be moulage lingerie oogoo, or maybe lingerie oogoo moulage.  Whatever. ( listen to "Waiting for the bus")

I was asked to put together a little first aid demo for the Scout Fall Camporee.  First aid training for young teens can be fatally boring, so there's nothing like some blood and guts to keep them awake. 

Moulage is the art of applying mock injuries for realistic first aid training.  The problem with traditional moulage kits are they're a little spendy, the the victims spend an hour in "make-up".  The latex or acrylic wounds have to be glued on, and blending in with grease paint, fake blood, etc.  I needed something that could be slipped on and off, cheap, and realistic enough  to make the kids think they were seeing something real.

I had played enough with Oogoo to understand the basic concept.  Fixed a few cords with it, made a few balls for fun, but this seemed like an ideal medium.  Sugru is great, but I needed large amounts.
Knowing that there is a Y-linked gene for affinity to the feel of women's nylons, the old lightbulb over the head went off.....................

Step 1: Materials

Oogoo is Silicon caulk mixed with cornstarch as a curing agent.  It is easily colored with oil based paint.

I made 3 open long bones, a sucking chest wound, a colles fracture, a 2nd degree burn, 2 stellate forehead lacs, and multiple assorted abrasions, lacerations and gunshot wounds from the following:

3 tubes of silicon caulking
1 box cornstarch
a handful of my beloved's fleshtone knee-highs, with runs
1 pair queen sized control top panty-hose
red, brown, and light yellow oil paints
1/2 inch PVC pipe
1 small plastic Halloween skeleton.
1 natural sponge
stretch wrap
plastic grocery bags

 
Forms for limbs were made by rolling up old towels, and wrapping them with stretch wrap to keep the silicon from sticking to the towels. A  Sleeping bag was used as a form for the chest wound.
Knee-highs work great for distal limb wounds, but for thigh wounds, use the legs from the pantyhose, as they are a little bigger.

Step 2: Cutting and Mixing

First, if you've never seen these wounds up close and personal, do a little research.  Lots of gory pictures on the web. 
The red paint on sale at Hobby Lobby appears a little light, so at show time, I'll dab it with a little fake blood.

Use some plastic halloween bones, or cut up a few pieces of PVC pipe for the bones.  I used a bandsaw and a dremel.

I've mixed uncolored oogoo before 1:1, and had no problems.  I thought I may need a little more working time, considering the large volumes, so for the first open femur, I mixed 1/3 cup cornstarch with 1 cup silicone.
Coloring is done with small amount of paint, a half inch ribbon on the tip of a popsicle stick of the brown, and a 1/4 inch ribbon of the yellow for the flesh tone.
1 cup was way more than I needed, and the1:3 ratio only gave me about 5 min easy working time.  You could do 2 or more long bones with 1 cup, but you'll need a helper.  After I got the bone glued to the stocking, and smoothed, the leftover oogoo was too thick to easily smooth.  So I put the rest in a plastic bag, rolled it out to 1/4-1/8 inch flat, and used it for lacerations and abrasions.

I first spread a thin layer of plain silicon on the stocking where the PVC was to be placed, to assure that the oogoo was well bonded to the stocking.  Probably not necessary if you work quickly and mix it right.

After I did a few of these, I stopped measuring and just eyeballed the amounts.  Regardless, the best working time was the first 3-5 minutes.

Step 3: Flesh Layer

The PVC or plastic bones are glued to the stocking with the flesh colored oogoo. 
A small piece of natural sponge lightly smeared with the red paint is used as bone marrow, subcutaneous fat, or lung tissue.

For the chest wound, I think a flesh colored tube top or something along that line may be more comfortable for the wearer.  Could have also used a 6in ace wrap, as they tend to be flesh colored.  I used what I had. 
I cut the legs off the pantyhose for the arms, and cut out the cotton panel for the neck.  A very tight fit, but it can be done.  A legitimate reason to put women's undergarments on your head..................

After you butter on the oogoo, it can be smoothed by misting with water or dusting with cornstarch, and smoothing with your fingers.
I think the cornstarch makes a smoother finish, but looks a little dusty.  Maybe a light wipe with baby oil before showtime.

Step 4: Add the Gore

Now mix up the red oogoo, again using just a tiny ribbon of red paint on a popsicle stick.  You won't need near as much.  Roll the leftover flat, and it will be used for other wounds.

Butter the red oogoo on, but don't smooth it much.  You want it to look like damaged stringy macerated tissue.

Step 5: Lacerations and Abrasions

A couple of ways to make lacerations.

When you roll out your flesh oogoo in a plastic bag, while still workable use a popsicle stick to form a groove, through the plastic, in the oogoo sheet.  After it's cured, peel it out of the plastic bag, and dab some red oogoo in the preformed groove.

I made the stellate lacerations by rolling out and curing a 1/4 inch flat piece of red oogoo, then cutting a stellate pattern out.
Then, place a piece of stocking on the form, glue the red stellate to the stocking, and butter over it with the flesh oogoo.  Then wrap that tightly with the stretch wrap, and with a popsicle stick force the still workable flesh oogoo from off of the top of the cured red oogoo.  After it's all cured,  used a dremel to rough up the red, again to look like macerated tissue.

For abrasions, simply smear the red lightly over the cured flesh.

Second degree burns can be made by using raw silicone dabbed or blobbed  onto cured flesh.  Sprinkle with cornstarch and gently flatten.

Step 6: Closed Fractures, Stabbing, Impalement, Gunshot, Etc.

Closed fractures are basically just deformities, and can be simulated by just a lump of flesh oogoo in the right place.  Over the dorsum of the wrist, it looks like a Colles' fracture. Cut finger holes in the end of the stocking and pull it on like a glove.

Make a wooden knife, or toy plastic knife, cut the blade to an appropriate length, and glue it to the stocking with flesh, put some red around the entrance. 
Do the same with a jagged piece of clear plastic, or anything else you can imagine.

Gunshot entrance wounds.  Flatten some workable flesh to abt 3 inches round, and using the end of a pencil make a small depression in the center.  When cured, dab a little red in the depression,  add some powdered graphite powder burns if you want.
Exit wounds are larger, with more tissue damage.  Make a larger flesh round,  with a center depression an inch or two in diameter, and fill it with a little sponge and unsmoothed red.

Step 7: Final Thoughts

To me, the beauty of this is it's incredibly easy to make, and using nylon stockings, incredibly easy to get the victims all moulaged up in just a few minutes.  There are no molds, nothing to glue, nothing to wipe up afterwards. And dirt cheap.  I made a dozen on a Saturday.
For those with some artist talent and familiarity with oil paints and pigments, you could probably come closer to tissue colors than I have with 3 tubes of paint. 

And yes, it is Halloween season.  I suppose you could make some pretty gory looking costumes.  I guess as an old ER doc, the last thing I want is to see my work show up on my doorstep begging for candy.

Hope this gives you some ideas.  If you feel inclined to vote in the Halloween Prop contest, I appreciate it.

We used to do something like this for the younger scouts to earn their first aid badges. We staged a bus wreck. We used a mix of flour and water to make the wounds, and make up to make them look real. Karo syrup , some dyed blue in the bottom of the wound, with red dyed at the surface, made it beyond believable. One year we set up with one kid to have a broken arm. After I applied the effect, he dislocated his arm at the elbow. None of us knew he was double jointed. It was real enough looking that some of the kids passed out. These are great looking effects. Its a great setup, and it would have been nice to have had some reusable effects.
