Encase Your Friends in Carbonite




Introduction: Encase Your Friends in Carbonite

About: I'm a wayward sailor lost in the midst of all manner of tinkering. When I was a kid I learned that the way to get the coolest toys is often to build them yourself. About that same time I decided to stop grow…

A while back a friend of mine asked me if I could help him builda replica of Han Solo encased in carbonite to hang on the wall in his basement bar (which he'd themed to look like the throne room of Jabba the Hutt).  So I told him I'd look into it and see what's involved.  While I was sitting in the cafe one morning, poring over photos of the original prop, my friend Jenny wandered in and asked what I was doing.  

So I told her.

"Can you really make that?" she asks.

"Sure," says I, "it's actually not such a big deal."

"Does it have to be Han Solo?" says she.

"No," I replied, "it's actually easier if it's someone who can come into the workshop for lifecasting.  That'll save me the trouble of finding or sculpting a copy of Harrison Ford's face."

"What if it was me?" says she.

The conversation ended with her gleefully agreeing to come to the workshop and put in all of the labor and pay for all of the materials required to make the project possible.  My role was to provide parts and technical advice.

Here's a picture of the finished product.  For more information on how it was made, read on...  

Step 1: Lifecasting Hands

In order to make an exact duplicate of someone's hand, the easiest (or at least cheapest) thing to use is called Dental Alginate.  This is a seaweed-based product used by dentists to take impressions of teeth and gums in order to make dentures or retainers or the like.  

The material itself is sold in a powdered form.  To use it, you mix it with water and it turns into a gooey mess with about the same viscosity as ketchup.  After a few minutes, it hardens into a rubbery solid.  It's safe to use in direct skin contact, and you can control how fast it cures by changing the temperature of the water that you mix it with.  Warmer = faster.

In order to make a copy of a hand, you mix up a batch of alginate in a bucket big enough to give you at least half an inch of clearance all the way around the appendage in question.  Then you stick your hand into the bucket, wiggle it around to work the bubbles away from your skin, assume whatever pose you want the duplicate to have, and wait until the alginate solidifies.

Here's a shot of Jenn
y showing us what her hand looks like:

After mixing up a batch of alginate, I had her insert said hand.  Here she is waiting for set-up time:
Hand Molding

Once the alginate has solidified, you need to gently remove the hand by wiggling and twisting and pulling until you break the vacuum and you can slide out.

Here's Jenny wiggling (always a fun thing to watch): Hand Removal

Once she'd slid her hand out, this was the hole that was left behind:

Hand Mold Hole

The little bumps you see on the left side of the hole are the pores in her skin.  The alginate picks up every fine detail.  So much so, that the resultant castings will actually have fingerprints that are identical to hers.

The one drawback to alginate is that, once it cures, it will shrink as the moisture dries out of it.  So it's important to pour the casting as soon as possible.  In this case I used black casting resin:Pouring Resin 2

During the pour, you have to tip the mold down toward the fingertip side in order to let any trapped bubbles out: Pouring Resin

Once the resin sets up, it's a simple matter of breaking apart the alginate and getting the cast resin piece out: Pulling Hand Cast

The result: a plastic hand identical to the original: Extra Hand

If you're making this same project at home, you need to repeat these steps as necessary for the number of hands your model has.

Step 2: Lifecasting the Face

Due to the potentially hazardous side effects brought on by suffocation, making a copy of someone's face is a tiny bit more difficult.  You still use dental alginate, but you can't just submerge their head and wait for it to cure.  There's a few other things involved too.

Here's the materials: Face Casting MaterialsPictured clockwise from bottom left are mixing sticks, a bag of powdered dental alginate, some paper towels, some mixing buckets, and a couple of different widths of plaster bandages.

You'll also need a pair of straws for your victim model to breathe through:
Breathing Straws

It's also a good idea to have your model wear a bald cap and coat their eyebrows and any facial hair with a healthy portion of moisturizing skin cream to keep the alginate from tugging at their hair.  Finally, you should place them in a comfortably reclined chair.

Since this project was done on the cheap and I'm an inconsiderate jerk, we taped a plastic bag over her hair and had her sit on a bucket with her head leaned back on a nearby folding table.  Good enough.

With all of that set up, it's time for the gloop:
Alginate Layer Buildup
In this case, since the desired duplicate will end up having a healthy dose of exposed cleavage, I also had to layer the alginate over a significant portion of her chest.  These are the sacrifices we make.

In order to speed up the process, you should mix the alginate with water that is at least lukewarm.  The warmer you make it, the faster the alginate will set up.  The trade-off is that you still need to give yourself enough time to get the whole job done before the alginate solidifies, so you don't want it to be too warm.

Once the alginate has set up, you need to build a layer of plaster bandages over it in order to support everything and maintain its shape once the person is removed from the inside.  

Again, warmer water will help speed up the process.  Here's the beginning of the plaster bandage layer being laid up: Plaster Bandages Begin
Work as quickly as possible to minimize the time your model will spend cocooned inside: Plaster Bandages Buildup
It's probably a good idea to ask long before you get to this point whether or not your model is claustrophobic.  

Just saying.

Using warmer water will help the plaster bandages cure faster.  You know the whole thing is solid enough to remove it from the model's face when it has cured to the point where you can write embarrassing things on it: 

With the plaster bandages hardened, have the model lean forward.  Once again, they'll have to wiggle and squirm until the alginate gives up its grip on the skin.  In this case, I told her to smile her way out of it: 
Removing Mold

While the model goes off to pick the alginate out of her hair and teeth, I coated the inside of the mold with resin: Pouring Resin 1
Then a bit more resin: Pouring Resin 3
When the resin was built up thick enough to support itself, it was time to remove the plaster shell: Cutting Plaster Off

With the plaster shell torn away, it was time to clear away the layer of alginate: Peeling Alginate

How did it come out? Let's check: Face Comparison
I see significant flaws.  The alginate had separated from the plaster shell around the nose and I didn't notice in order to push it back into proper alignment.  The result was a somewhat pug-nosed casting with the nose and upper lip pushed in.  There was also a split in the mold along the left cheek that resulted in a somewhat excessive ridge on that side.

We can fix it.

Step 3: Clean Up the Castings

Having identified problem areas in the casting, it's time to start fixing them.

First step: cleaning out the nostril plugs.  If you've ever wanted to take a power drill to someone's face, now's your chance:Nostril Cleaning

Next step: adding a bit of Bondo auto body filler to straighten out the squished nose:
New Nose in Bondo

It's a good idea to keep the original close at hand so you can make regular comparisons: New Nose Comparison

While the Bondo is still soft, you can get away with doing fine-tuning with a knife.  Do not attempt this on the original: New Nose Rough Shaping

Once the Bondo has hardened further, you can do more fine-tuning with coarse sandpaper (also not a good idea to try this on the original):
New Nose Sanding

When it seems like you're done, you can spray on a quick coat of primer to check the shape: New Nose in Primer

Good enough.

Step 4: Build the Box

Before starting this project, I did quite a bit of research into the design and construction of the original, screen-used prop.  Some of the most useful information can be found in the relevant discussion threads at the Dented Helmet, which is the Boba Fett costuming forum.  So click that link if you want to know everything there is to know about the original piece and see how a few other makers have replicated it.  At the bottom of this page is a painstakingly researched set of blueprints with all of the dimensions of the box itself which came from that thread.

The original piece was tapered slightly from bottom to top.  It was also slightly tapered from back to front.  Since this was a rush project and there was no reason to go completely insane matching all of the angles, I decided against making screen-accurate tapered sides. I also re-sized the whole piece because Jenny is quite a bit shorter than Harrison Ford was when they built the original.

So I drew up a simplified template to match the look of the original while eliminating some of the less important details.  Here she is laying out the cutouts that will go on the sides of the box: 
Laying Out Cutouts
Because she was providing all of the labor, she was supposed to do all of the cutting and drilling.  Unfortunately, at this point she had almost no power tool experience, so she needed to be watched in order to prevent her from drilling holes into her hands or, worse, something expensive.

Here she is drilling starter holes: This is a Drill
With the starter holes drilled, it was time for her to learnto use the jigsaw: Jen with Jigsaw
Here's a side piece all cut out: Box SideSome of the edges are even kinda straight.

Once the parts were all cut out, all of the seams were glued together with Gorilla Glue:
Gluing Box Joints

NOTE: Gorilla Glue will stick to your hands and make a tacky mess that will turn black with dirt and not wash off until you've scrubbed off the skin that it's attached to.  Usually it'll take a week or two to get it all off.  If you're not ready for that level of commitment in an adhesive/skin relationship, wear gloves.

In addition to the glue, they were screwed together too:
Box Corner

Here's the first three sides of the box coming together: 
Nearly There
There was a fourth side too, but I neglected to take a picture when it was attached.

Step 5: Attach the Body Parts

Once the box was assembled, I had to have her test it for proper size: 
Size Testing

After adjusting her position to match the pose from the original, I traced the outline of her body on the front panel:
Body Outline Carved

Standing the whole thing upright, I glue the lifecast parts onto the surface, then screwed them on from behind: Screwing Left Arm in Place

Screwing Right Arm in Place
This is about the time that this thing became large enough to be a nuisance filling up space in the workshop, so it was time to speed up the rest of the build.

Part 4: the Body

The next step was building up the parts of the body that would be covered in clothing. Since they would be covered, there was no need to go through the lifecasting process. Instead, I sculpted these parts from scratch. I started by mixing a batch of expanding foam: Mixing Foam

Then poured it into the outlined area: Pouring Foam
Since the first batch was too small, I went ahead and poured another batch on top of it: Pouring More Foam

After about an hour it had expanded to full size and hardened enough to start shaping: Foam Expanded
Rough shaping was achieved with a kitchen knife: Body Carving

Smoothing and finer shaping was done with a body rasp: Body Rasp

After a few minutes of work, I had a reasonable facsimile:

Jen Comparison

To trim the outline of the front panel, I cut strips of 1/2" MDF sheet:
Jen Carbonite 24

These strips were then glued and screwed onto the surface:
Jen Carbonite 25

With that, the bodybuilding was done.  It's considered poor form to encase someone in carbonite when they're nude, so the next step was dressing up the body.

Step 6: Dress the Body and Make It Solid

In this case, the donor dress was actually chosen very early on in the design process.  Since only the front third or so of the body will be visible in the finished piece, the rest of the dress had to be cut away and discarded:
Jen Carbonite 23

With the unnecessary parts of the dress removed, the next step was to drape the remainder over the body and  decide how the fabric will fall:
Jen Carbonite 26

Once I was satisfied with the look of the dress, the next step was to coat the foam body form with a batch of urethane casting resin:
Jen Carbonite 27

Working as quickly as I could, I re-draped the dress and soaked the fabric with more resin:
Jen Carbonite 28

Here you can see the resin turning off-white as it starts to cure:
Jen Carbonite 29

I mixed a couple of smaller batches of resin and used them to add texture to the flat open areas on the front of the piece.  The goal was to stir up and stipple and puddle the resin so that there were no smooth areas left on the front panel.

With that done, all that remained was to mix a couple of batches of Bondo and fake a quick and simple hairdo:
Jen Carbonite 30

Then it all got a good coat of black primer:
Jen Carbonite 31

Here's a full-length shot:
Jen Carbonite 32

With the big parts done, now it's time to focus on the small parts.

Step 7: Add the Little Details

The indicator panels on the side of the film-used prop were actually dashboard panels taken out of a 1978 Volvo, which were then molded and cast.  I don't have any old Volvos in my workshop, so I had to resort to just making something up.

I tasked Jenny with finding a photo of one of the original panels.  Then I handed her a block of MDF and told her to add sheet plastic to it and cut in windows so it would look as close as possible to the original.  Here she is in the middle of that process:
Prototyping Display Panel

I also had her cut panels out of 1/2" MDF to match the holes in the side panels: Cutting Out Inset Panels

Here's one of them fitted in place before being pushed in for an adequate recess:

Inset Panel Test Fit

The original display panel Jenny made was molded and eight copies were cast in urethane resin.   Matt Making Lights

Holes were drilled randomly in the display panels and we wired them up with LEDs:

Lots of LEDs:
JIC Control Panels Left

Seriously.  Lots:
JIC Control Panels Right

Some of them were blinking LEDs, some of them were high-intensity, all of them were completely added at random.  Once the wiring was done, scraps of tinted acrylic were cut out to fit into the display windows and make them look a little less cheesy.  Then we took some random small parts left over from the Ghostbusters project and glued them on to make the panels a tiny bit more interesting.

Here's what it looked like after it was painted:
Jenny in Carbonite Finished Left

JIC Left Display Panels

Here's some closeup shots of the panels:
Control Panel Closeup 3

Display Panel Closeup 1

Oh, right.  I haven't described the painting process...

Step 8: Paint

This is the part where we take this amalgamated mess of pieces and parts and various materials and make it look like some sort of dark grey metal similar to pewter

The whole process began with a few coats of silver spraypaint:
JIC Jen Spraying Silver

JIC Silver

In between coats, Jenny put another layer of filler on the visible screw holes:
Jen Filling Holes

When the base color was completely done, it looked like so:
JIC Silver full length

Once the silver had had plenty of time to dry, it was time for a blackwash.  This would darken the color and bring out all of the various details and textures.  In this case, I began by slathering it with black acrylic paint:
JIC Blackwash Begins 1

Jenny spread the acrylic paint over the whole thing:
JIC Blackwash Begins

Before the paint had any time to dry, the next step was to water it down and then wipe, dab, spread, and smear it all over with very damp rags:
JIC Blackwash In Progress

As the paint started to dry, we gradually switched to dryer and dryer rags until we were buffing nearly dry paint off of the highest surfaces and most prominent details.  The resulting finish looked like so:
JIC Blackwash Complete

JIC Blackwash Complete Closeup

I think we managed a fairly decent approximation of the look of the original:
JIC Blackwash Complete Closeup Right

With the look of the outside all taken care of, it's time to figure out how the whole thing will work.

Step 9: Make It Functional

I forgot to mention it has shelves inside:

The recessed panels that the display panels are attached to are actually hinged:JIC Door Hinges

Hinge installation gave Jenny another excuse to use power tools and frighten everyone within arm's reach:
JIC Dewalt Tools

JIC Door Blocks

With all of the shelves installed and the hinges mounted, it was time to close up the back and fit it with cleats for hanging it on the wall:
Mounting Cleats

Finally complete, all that was left was to load up "Jenny in the block" for delivery:
Loaded for Delivery

Once we had it in the back of the truck, I donned my Boba Fett helmet and we paraded it all the way through town before heading over to her house and surprising her with the finished piece (by leaving it there when she wasn't home).

Mission accomplished.

    Great project, but you shouldn't use straws in the nose, although unlikely think what would happen if you knocked a straw up the nose. As a FX artist and Association of Life Casters International member I always see where there could be a potential health and safety problem. Even the best in the FX world make sure to have an assistant for facial lifecasts, someone whose only job is to keep the nostrils clear, another hint is to make sure you arrange hand signals with your model so you can check as you go along that they are still OK. Dental alginate is great but people with sensitive skin may have a reaction to the menthol thats added so its better to use something like Mouldlife alginate or Tiranti's as these have nothing perfumed added.


    Reply 9 years ago on Introduction

    We had the top end of the straws pretty thoroughly wrapped with gauze to make sure it wasn't going anywhere, but I see your concern.

    Also, I neglected to mention it, but we had a couple of emergency signals worked out in advance. For calmer, more nuanced communications, I had her close her eyes and try writing with a paper and pencil before we started. Turns out she could write legibly while blinded, so she had a clipboard and pencil on her lap throughout the face casting process.


    Reply 9 years ago on Introduction

    Cool, I did see that but just wanted to mention it for anyone who has never done it before - i'm of the mind that if you think of anything that can go wrong even the most unlikely things and plan for it, it will never be a problem.

    That's great as well that you thought of your models safety and did hand signals/blind writing.

    And I really do love the project :)

    Some people have waaaaaaay too much time on their hands. Awesome work!


    Reply 5 years ago

    As a person who is also artsy and project oriented, I hate it when people say you have too much time on your hands. It's very demeaning. We have the same amount of time as everyone else. When you're passion is art, it's how you choose to spend your time. Some people play video games which in my opinion is a bigger waste of time. He ended up with an awesome project so it was time well spent!


    Reply 5 years ago

    I didn't mean to put down anyone's work, I was joking. It is a terrific project (but it obviously took a lot of time). The unkind message my comment projected was not intentional :)

    I also like this instructable!
    Jenny you have very beautiful pores. And a glowing persona!
    Thorssoli, you have a lovely assistant.
    It has been years gone by apparently? What is Jenny doing now days?


    6 years ago

    Very interesting . Where would one buy dental alginate ?. Anyone else know of a liquid plastic which is as resilient as polyprop (2) and can be cast in a mold like this . Preferably fast setting . I want to replicate remote control buttons . They seem to be made out of a rubbery substance that goes tacky and perishes after a year or two .


    6 years ago

    Not only was this a fabulous project... but it was a really great read too... I love your sense of humor! And... very educational... I would have done the whole body lifecast, used Ultracal, etc... your method was much simpler with the expanding urethane. Very nicely done! And... you managed to teach Jenny about power tools and lived to tell the tale. (grin)

    I love this instructable!!! Ive been a member of instructables.com for a number of years... and this is my first comment.

    I am sooooo sick of reading unbelievable instructables such as this one - with 80+ percent of the comments being either hasty psuedo science ("toxins/harmful/blah blah blah") or those arguing against them. No comment aside from "wow" should be tolerated in this post.

    9 years ago on Introduction

    That is awesome but what would that cost for one of us normal folks without all the goodies to work with i seen a bunch of gnome statues in the background i presume you make fiberglass things for a living ? what would the cost of that project be ?


    Reply 9 years ago on Introduction

    Cost for this project? One sheet of MDF, about a gallon of casting resin (two gallons costs around $120 or so), a few ounces of expanding foam, one dress, and a handful of LEDs.

    You could probably use less than $500 in materials.

    The gnomes are one of the many things I make. You can find them in my Etsy shop: https://www.etsy.com/shop/thorssoli
