Step 1: Materials Used

Picture of Materials Used
Materials used:

1 or more cans of spray foam insulation

1 or more orange string lights

plastic bottles

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

Picture of 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.

were theses steady state lights or twinkle lights?

have you tried with twinkle lights?

and what if you mixed red, white, yellow, orange, and possibly even blue lights all together?

jzuwala motts (author)  RenMandFx1 month ago

they were steady but twinkle should work just fine. I like the idea of mixing different colored lights, that should produce some interesting results.

I'm thinking used that dried moss stuff & give it a light coating of spray paint for even more texture & interest. This is very very cool!

You could do this in another way and for other reasons. Like for a fake fire in your fireplace in summer time. That way you wont have to deal with your energy bill going up if you need a special addition to a party or romantic night.

Mine had more of the look of red hot coals. Not very hard though!

cool idea. Will the lights melt the plastic if it's on for a long time?

If you change the colors and final layers slightly it would be possible to have the effect of a melting corpse or monster.
