In this instructable I will show you how to build a smoldering pile of embers prop. Use it under a cauldron, burnt corpse etc.
Step 1: Materials Used
1 or more cans of spray foam insulation
1 or more orange string lights
plastic floor liner
1 roll clear packing tape
1 can of Grey primer spray paint
1 can black spray paint
1 can red spray paint
1 can rubberized undercoating
Step 2: Preparing the Lights
Cut a few plastic bottles open, removing the bottoms and tops.
You can also use larger bottles by slicing down the side as well and rolling them up to the desired size.
Run your string lights through these bottles. Perfection isn't required and some lights outside the bottles is ok, just try to to have most of them inside.
Alternatively you can use clear plastic sheeting such as plastic drop cloth available in your local hardware stores painting section.
I used both methods in the above example.
If using plastic, roll it up around the lights and tape in place with the packaging tape.
Form a circle with the lights as best you can and curl the end into the center of the circle.
Use the packing tape to hold everything in place.
Step 3: Spray Foam Insulation Onto Lights
Cover the lights with the spray insulation. You don't need to cover it with a thick layer, just enough to hide the plastic sheeting and or bottles. Remember we want to see the light.
While it's dying you can tap at it with the foam cans tip to roughen up the texture. Be careful this crap gets everywhere if your not carefull.
You can also add bits of wood or charcoal to the foam at this time before it dries.
Step 4: What It Looks Like So Far
At this point it lights up very bright in the dark and looks like a pile of white hot coals. Its possible to stop here and use as is, If your not planning to have your props out before Halloween day that is... it will need more work if it's to be seen in daylight and not just in the dark of night.
Step 5: Paint the Foam
Once the primer is dry it's time to paint the foam.
First apply a layer of fire red, once that's dry apply the black spray paint leaving about half still showing red.
Step 6: Apply Rubber and Ash
Grab the rubberized undercoating, holding the can about a foot away spray the surface with a light spattering of the rubber. Immediately pour ash all over the surface you just sprayed.
Once that's done spray another light coating of rubber on top of the ash.
Wait a minute to for it all to dry. Once dry turn over and shake off the access ash.
This step can be repeated if it didn't hold onto enough ash.
Step 7: Finished Embers, Possible Uses
Here is what they look like when finished. I included a few pictures of a burn corpse i made laid over the coals as an idea of how this prop could be implemented in your haunted house or halloween decorations.
