DIY Fallout Bomb Prop





Introduction: DIY Fallout Bomb Prop

About: I've always been a very creative person and a self confessed video gaming geek. I'm a husband, father, artist and blogger

In this awesome instructable I'll show you how I made a bomb/nuke prop from the video game Fallout.

Things Needed

  • One large plastic easter egg
  • One foam matt (only need about 10% of it)
  • PVA (white glue)
  • Hot glue and gun
  • Super glue
  • Eight flat head screws
  • Grey primer spray paint
  • Acrylic paint
  • Enamel Paint
  • Sandpaper (120 grit)
  • Permanent marker pen (black & orange)
  • Hand drill

Before you start I recommend watching the short video tutorial on how to make this for a better understanding. Making a Fallout Bomb Prop

Step 1: Making the Main Body

To start, super glue the two parts of the plastic egg together.

Next cut a 3 inch strip of the foam matt. Measure the circumference of the egg by wrapping the foam strip around and cutting to length. (see image)

Measure four equal steps and cut out. Connect end to end using hot glue. (see image)

Now measure four 3.5 x 1.5 inch foam matt. These will serve as the mounts. I found the best way to copy the shape of the egg is to hold just behind and follow line. (see image)

Once you have all the foam parts hot glue them all together.

Next mark out and drill eight equal holes around the egg. Screw in your flat head screws.

Step 2: Paint Prep

Using PVA glue paint the piece of foam matt . This is an important stage as it helps with spray paint and acrylic.

You will need about 3 layers of PVA, leaving each layer to dry before adding the next.

Also it's a good idea to rough up the that nice smooth easter egg using sandpaper, this also helps with the painting stage.

Once ready give the whole thing a coat of grey primer .

Step 3: Painting & Detail

Now for the best part, bringing it to life.

Using acrylic, paint the whole thing a military green. Dry brush a reddish brown in random areas (see image)

I use black enamel paint for the hard to reach corners, paint on and rub off, smudging it if you like. (see image)

Next I used yellow enamel for the stripe and triangle.

Using acrylic (metallic silver) I gave the whole thing a brushed metal look, this was done with a dry brush technique.

To finish I use black permanent marker pen for detail and orange for rust. (see last image)

    This is very well done! An awesome project and well explained. Think I will have to try one. Is PVA (white glue) that you refer to the same as Elmers white school glue, the type usually used for paper?

    Yes I believe most "white glue" is PVA water based.

    Polyvinyl Acetate commonly referred to as wood glue, white glue, carpenter's glue,school glue, Elmer's glue in the US

    I personally use decorators version of PVA for the waterproof elastic layer.

    Hope this helps and thanks again.

    Most wood glue is aliphatic resin instead of PVA.

    Am I the only person who knows you can buy one like this but official at GameStop?

    This is cheaper. And a lot of people find enjoyment in creating things.

    I love your work especially the fallout props I thought I'd show you some of mine :)



    I hope you don't live in Texas. ;)

    Great job! Looks amazing! What is the size of the egg? thanks!

    Looks legit. Probably should avoid walking through the airport holding this thing.

    Good one!

    Or, find an old smoke alarm, remove the guts and place the circuit board inside the egg. That way, when someone puts a geiger-counter up to it, it'll register from the infinitesimal amount of Americium found in many smoke detectors.


    And then when the smoke alarm goes off, everyone ducks for cover.


    Great project! I'm thinking about doing this, but since a "real" suitcase nuke would be fairly heavy, I would add some weight by filling the plastic egg with something like concrete, drywall "mud" or even RTV.

    Nice job, BTW.

    DONT take these to school kiddies!!

    Oustanding! and also very scary looking. Well done!
