Picture of How to make a Portal Gun
This is how I went about making my own Aperture Science Handheld Portal Device.

Ever wanted to run around a death chamber in an orange jumpsuit but never had the means to think with portals? Well now you can give it a go; perhaps. This is just one of the examples I hope to use to get into the Props and Special Effects industry *wink wink*. Rate it if you like it please.

Step 1: Starting steps

Picture of Starting steps
To start this, I needed to do some research to get some good views of the Portal Gun other than the POV postion behind the device. These three pictures taken from the internet were the best examples I could find to get an idea of what the whole gun looks like. The first image is an artist's impression which is fairly accurate so I used it as my scale drawing.

Assuming the gun would be approximately 500mm in length, I scaled the first image up in Microsoft Word and then just drew lines to find measurements to get an accurate model. Then using the other screen shots, fill in the details.

The cake itself isn't a lie. its a lie that GLaDOS will give you the cake
cool as hell i made mine with your desine exept with pvc insted of wood it cam out perfectly

Nice! this must have given you a lot of lemons. but when a project gives you lemons don't make lemonade! burn somebody's house down! WITH THE LEMONS!!!!!!!!!

I agree with ya. When life gives you lemons, don't make lemonade, make life take the lemons back, get mad, I don't want your damn lemons what am I supposed to do with these!?!? I demand to see life's manager, make life rue the day and thought it could give Lance Newman lemons, do you know who I am?!? I'm the man that's going to burn your house down, with the lemons, I'm going to invent a combustible lemon that burns your house down!!!!!!!!!!!!!!!!!!!!!!
How much did this cost?

£10-ish? A lot of it comes from found materials like the can, paint and foam. The main purchases were the chicken wire for the shell and the tubes for the body. It's really more or a Blue Peter scrap build than a professional prop. Make the best with what you have.

the cake is not a lie but on portal 2 it is
Son, you made a nice Gun! Your use of metal mesh (metal Lathe) was brilliant! I'm thinking you may want to use 'Bondo' instead of paper mache in the future. With a bit of practice and experimentation, you'll find you get a much more durable part and a smoother paint surface using bondo. Also head over to your local DIY Center and check out the ABS and PVC Plumbing pipes and fittings...Study them and mess around with them a bit! Awesome amount of possibilities! All and all. pretty nice!
i want it
can i buy?
This is awesome! Here's mine:

thank you for making the aperture extra-compact hand-held portal device
At this point i'd recommend putting Bondo on there ,bondo is amazing for this type of work. you can sand it to be incredibly smooth then all you need to do is prime and paint it.
Looks like a camera I'll make this and fit a camera inside.:)

Just wanted to say thanks for this tutorial. I made my own portal gun following your instructions and it turned out pretty good. Keep on making tutorials like this one. Detailed pictures of my portal gun can be found here: http://terno.1g.fi/kuvat/Aperture+Science+Handheld+Portal+Device+DIY/

what is the clear plastic cylinder made of?
Umm... Plastic?
what do you mean? is it not plastic?
What he meant was that you said- "What is the clear PLASTIC thing MADE OF" which made no sense, because you just said the answer. It's like saying "Hey, what's your name, Joe?" I'm just stating that, I'm not trying to be rude in any way.
I meant like a water bottle, a sheet of plastic rolled up, etc
OH, O.K, sorry.
chiok (author)  William9304 years ago
A sheet of clear polypropylene (PP). 700 microns thick I think. Available in places like Paperchase or in the packaging of large gifts, like a large photo frame or an ornamental duck.

can i use a plastic bottle instead?
chiok (author)  ahmad21174 years ago
Absolutely. It's a different material (PET, or HDPE) but it does the same thing, it's clear plastic. If you're happy with it, then go for it.

Interestingly, bottles made from PET like soda bottles, can be used to purify water if the bottle is clean and the filled bottles are left in the sun. Called "Solar Water Disinfection".

Can you upload a picture of the gun held in your hands? I want to see how big it is in relation to a person
chiok (author)  hampst5 years ago
I'm afraid not, it's in irreparable condition now.  It was 500mm in length, which in retrospect is too large.  Resizing the original reference image to 400mm in length would probably yield a more suitable size for a person of Chell's size.
