This is how i made my portal gun for halloween 2011.

it is one of many way that you can make a portal gun. i made it this way because my experiances with these materials were higher than any other method. 


Ive entered this to the Hurricane Lasers Contest, if you like it enough could you please vote for me at the top of this page.. Thank you in advance. :D

Step 1: Materials

Blue insulation foam for the main shells of the gun.

the barrel and body were made from PVC pipes at 110mm and 70mm  and one clear 65mm tube. also a solid clear acrylic rod at 20mm

plastic acrylic sheet for detailing parts.

three black cables (thick electrical cable is fine) and wire to put inside.  or three wire core foam wrapping strips (like the hair curling things. i found mind at a general store or DIY store)


for the electronics i had two bright blue LEDs and two red LEDs (shoud be orange but i didnt have any) a three way switch, an assortment of wire and a 9volt battery.

emulsion paint, filler primer spray paint, plastic primer spray paint, lots of white spray paint and black spray paint.

car body filler (most commonly called bondo) i used P38 polyester filler.

Glue! lots of glue ranging from two part epoxie and super glue.

also masking tape.

Step 2: Tools.

the tools used for this project were:

belt sander, jigsaw, hacksaw blade and lots of craft knifes.

losts of different grade sand paper: corse to very fine.

soldering iron for the wiring.

lots of clamps.

KylerM KylerM1 month ago

If not, what thickness was the foam? Do you think perhaps you could find me a link? Thanks.

Do not look directly into the operational end of the device.

Or submerge the device in liquid.

Even partially. Most importantly, under no circimstances shouLD y00̴̐̓ư̮̞̹̰̟̯̾ͥ̓̎̏ͬu̬̠̖͚̇͛ͤ͌̂ͅu̡͔̹͈͙͙̦̇̌͛͂͡u̷̵̧̺̞̲ͧͤ̐̂͌̐ų̺̳̰̫̪͋ͮ̄́ͮ͘ų̬̼̹̩̘̓ͫ̌͝ <STATIC>

Well here we are again

It's always such a pleasure

Remember when you tried to kill me twice?

Oh, how we laughed and laughed. Except I wasn't laughing.

Hey, backwards lamb! Cool prop! Maybe I'll try to make one! :)

backwards lamb (author)  GeekKiD20033 months ago

do it, give it a go. If you do share a picture so we can see :)

goes through portals on ceiling and floor ......... weeeeeeeeee!

Now your stuck. How do you get out? Think about it, falling at terminal velocity (and how it sucks).

How thick was the Blue foam you used?
How long should the shells be? Also, how long is the portal gun itself?

how much would it cost to make if you didn't Have any of the parts already?
backwards lamb (author)  janafekin1 year ago
i honestly couldn't tell you im afraid. as i did have nearly all the stuff or got it from friends as scrap i dont know how much the parts would cost. sorry
wait sorry, where did you buy the acrylic hook connecters?
backwards lamb (author)  Fastndfurious1 year ago
Which parts do you mean? The tabs that have a hole through where the front claws connect to with a bolt? If yes, I made them out of acrylic sheet cut out on a laser cutter
How did you make the claws on the front?
backwards lamb (author)  Fastndfurious1 year ago
They were made from acrylic sheet cut out on a laser cutter.

i really like the look of the main shells. they look just glossy enough. one question though, how strong is the foam? also, is it very porous like other foams?
i have never used insulation foam so if it is easy i just might start.
backwards lamb (author)  nerd121 year ago
The foam isn't too porous. It's a very hard dense foam. Closed cell I think is a word used to describe it sometimes.

It's a very easy material to work with. You can get good results with it if you spend time on it.
Please can anyone tell me where you got the foam from?
backwards lamb (author)  generaldidsy2 years ago
i got this foam from ebay, but model shops and DIY shops have it.

How or where did you get your Logos?
backwards lamb (author)  baterman2 years ago
I made them my self. I got the logo from the Internet and traced round it and then cut it out from vinyl sticker sheet.

Cool project. I went to your flicker site. Your Fallen Angel paintings on skateboards are excting to look at! Wow!
I've got the main part done...I just can't find something good to build the white part. How's the paint holding up on the insulation?
backwards lamb (author)  mr monoply332 years ago
very well, if you get enough sealing done with acrylic paint and filler it will hold up.

it wont hold up to being smashed about. but they are pretty strong.
